PUBLIC SAFETY AND HOMELAND SECURITY BUREAU SEEKS COMMENT ON 9-1-1
RESILIENCY AND RELIABILITY IN WAKE OF JUNE 29, 2012, DERECHO STORM IN
CENTRAL, MID-ATLANTIC, AND NORTHEASTERN UNITED STATES
PS Docket No. 11-60
Comments Due: August 17, 2012
Reply Comments Due: September 4, 2012
IntroductionOn June 29, 2012, a fast-moving weather storm called a derecho brought a wave of destruction
across wide swaths of the United States, beginning in the Midwest and continuing through the mid-
Atlantic and Northeastern regions of the country. Millions of Americans lost electrical power during the
storm for periods ranging from a few hours to over a week in the middle of a heat wave, and the storm
caused billions of dollars in physical damage. The storm had a significant adverse effect on
communications services generally and 9-1-1 facilities particularly.1 From isolated breakdowns in Ohio,
Kentucky, Indiana, and Pennsylvania, to systemic failures in northern Virginia and West Virginia, it
appears that a significant number of 9-1-1 systems and services were partially or completely down for
The impact of the storm in northern Virginia was particularly severe, notably in Fairfax County,
parts of Prince William County, Manassas Park and Manassas, where over 1 million people faced the
possibility of not being able to call 9-1-1 successfully.2 In those jurisdictions, media reports and local
government officials indicate that public safety answering points (PSAPs), which process calls to 911
facilities, failed, as did backup systems. Multiple access technologies appear to have been affected by the
outages, including traditional networks, broadband networks, and wireless networks.
The Public Safety and Homeland Security Bureau (PSHSB or Bureau) of the Federal
Communications Commission (FCC or Commission) responded immediately, closely coordinating with
the Federal Emergency Management Agency (FEMA) and constantly communicating with service
providers and other stakeholders from the time the storm hit and throughout the period impacts were felt
by the public. At noon on Saturday, June 30, the Commission granted an emergency special temporary
authorization allowing a Missouri power company crew to use certain frequencies to assist in the
restoration of electric power within the Ohio disaster area.

Utilizing the Commission’s Operations Center, which is staffed 24 hours a day/7 days a week,
and supplementing it with direct outreach and pre-established reporting protocols, the Commission
obtained important information on communications outages related to 9-1-1 centers, broadcast stations,
and public safety communications systems that it shared with its Federal partners (e.g., FEMA). Vital
information on outages also came through the Commission’s mandatory Network Outage Reporting
System (NORS) and voluntary Disaster Information Reporting System (DIRS). At 5:15 p.m. on
Saturday, June 30, the Commission activated DIRS, targeting selected providers with systems in the
disaster area, in this case the District of Columbia and certain counties in Maryland, Virginia, and West
Virginia. Through DIRS, the Commission received regular updates on the status of wireline, wireless,
and 9-1-1 communications outages and restoration efforts. As company maintenance crews largely
restored communications services in certain areas, the Commission de-activated DIRS for those areas on
July 3, 2012 and completely deactivated it on July 4, 2012. The Commission also issued on its website
and distributed through social media a consumer tip sheet for the public about communicating after the
derecho, while the effects of the storm were still being felt.
Immediately after communications and 9-1-1 services were restored, the Bureau began an inquiry
focused on learning all of the facts and circumstances of the various outages, including the causes and,
importantly, ways to make the public safer and avoid future outages. The Bureau began an ongoing series
of meetings with stakeholders, such as communications service providers, public safety officials, and
others, and continues to seek and obtain relevant information. The Bureau is assessing and evaluating the
storm-related information received through NORS or DIRS, and still coming in through NORS. The
Bureau is also coordinating with state and local governments, which are responsible for establishing and
operating 9-1-1 facilities, providing first responder services, and regulating certain relevant
By this Public Notice, the Commission and the Bureau further expand the ongoing inquiry. The
Public Notice broadens the inquiry in two ways, by expanding those who may contribute relevant
information to include the public, and focusing not only on issues directly surrounding the derecho and
what happened during and after it, but also on other experiences associated with natural disasters
throughout the nation that involve outages or are otherwise related to the resiliency and reliability of
communications services and networks of all kinds that are used to seek, process or obtain emergency
assistance. Especially in the face of events that lead more people than usual to need emergency help, they
must be able to connect to get it. It is vital to seek focused comments broadly on what happened during
and after this or other storms, and what can be done to better address these issues going forward.
Congress has given the Commission a particular responsibility under the Communications Act to
ensure communications networks of all types “promot[e] safety of life and property.”3 Central to this
important responsibility is ensuring the reliability, resiliency and availability of communications networks
in times of emergency, including and especially during and immediately after a natural disaster such as a
derecho. Recognizing this, last year the Commission initiated a proceeding on the reliability and
3 See 47 U.S.C. § 151; see also 47 U.S.C. § 154 (o) (“For the purpose of obtaining maximum effectiveness from the
use of radio and wire communications in connection with safety of life and property, the Commission shall
investigate and study all phases of the problem and the best methods of obtaining the cooperation and coordination
of these systems.”) In addition, the Commission recently strengthened its outage reporting requirements by
extending them to interconnected VoIP services. See In the Matter of the Proposed Extension of Part 4 of the
Commission’s Rules Regarding Outage Reporting To Interconnected Voice Over Internet Protocol Service
Providers and Broadband Internet Service Providers, PS Docket No. 11-82, 27 FCC Rcd 2650 (2012).
continuity of communications networks, including broadband technologies.4 Information received in
connection with this Public Notice will add important information that will inform the Commission’s
action in this proceeding.
Request for CommentThe Bureau seeks comment on the background, causes, and restoration efforts related to
communications services and facilities impacted directly or indirectly by the storm and after. It seeks to
develop a complete and accurate record of all the facts surrounding the outages during this storm as well
as outages resulting from natural disasters in order to evaluate the overall resiliency and reliability of our
Nation’s 9-1-1 systems and services. We also seek comment on the impact these outages had on the
various segments of the public, including consumers, hospitals, and public safety entities.
The Bureau’s review is also intended to further develop the record in the Commission’s ongoing
examination of issues in the April 2011 notice of inquiry (NOI) on the resiliency, reliability and
continuity abilities of communications network, including broadband technologies,5 and comments
received in response to this Public Notice will become part of the record of the NOI. In that proceeding,
the Commission initiated a comprehensive examination of these issues with the goal of determining what
action, if any, the Commission should take to ensure that our Nation’s communications infrastructure is as
reliable as possible and able to continue to function in times of emergency. In its NOI, the Commission
also focused on 9-1-1 reliability and stated that “[p]eople dialing 9-1-1, whether using legacy or
broadband-based networks, must be able to reach emergency personnel for assistance; and when networks
dedicated to public safety become unavailable, first responders must have access to commercial
communications, including broadband technologies, to coordinate their rescue and recovery efforts.”6
Questions Regarding Derecho Impact, Effects, and Restoration EffortsBelow, the Bureau poses a series of questions related to the impact of the storm on emergency
and 9-1-1 communications accessed by traditional communications networks, broadband communications
networks, and wireless communications networks. The Bureau also requests comment on the storm’s
impact on various user groups. PSHSB seeks comment on the following issues:
Causes of Outages. What were the specific causes of the outages that occurred during or after the
storms? Which network elements and components, such as Public Switched Telephone Network (PSTN)
trunks, Internet-Protocol (IP) broadband access lines, databases and PSTN switches, were out of service
and for how long? For example, to what extent were issues like powering, physical damage, and power
surges contributing factors to the outages? To what extent are there industry best practices that address
these, and any other, contributing causes? To what extent were they followed?
In what ways was physical damage due to the storm a major cause of outages? What could be
done to improve the resiliency of communications infrastructure in the face of physical damage like what
was seen during the storm? Are there actions the communications industry can take to avoid or mitigate

these outages in future similar events? Should the FCC take other steps to improve communications
resiliency during strong storms like this?
In what ways was the derecho an “extraordinary” event? For example, compared to other types
of disasters, did it occur with unusually short notice, affect an unusually large area, and was it unusually
intense? How did these factors inhibit service providers in responding to the event and restoring service?
How did these factors affect consumers’ need for communications services and ability to obtain
emergency services? What could be done to better prepare for events like this in the future? Specifically,
what actions should communications service providers and PSAPs take to better prepare for similar
events in the future?
How did service providers become aware that 9-1-1 outages had occurred? What types of
monitoring systems were in place for various types of assets, both in the field and inside buildings? How
well did these monitoring systems perform during the storm?
What role did the availability or absence of back-up power for network equipment play in the
9-1-1 outages that occurred during the storm? What could be done to improve the ability of
communications assets to operate longer when commercial power is lost? Are there new technologies,
such as solar and fuel cells, which provide promise in this area? What maintenance practices are in place
to compensate for the loss of commercial power? How did these methods perform during the storm? Are
there actions the FCC should take to improve the ability of communications networks to survive
commercial power outages? What types of measures could be taken to improve the robustness of
communications infrastructure in response to failures of commercial power? Should the Commission
consider taking action, either voluntary or mandatory, that would address back-up power?
What forms of network interconnection, both PSTN and IP, were affected by the storm or loss of
power? How and why were they affected? Did these disruptions affect communications seeking 911 or
other emergency assistance and how? What carrier and public safety facilities have multiple means or
forms of interconnection and which do not? Which of these facilities are essential for 911
communications? What monitoring of interconnection was in place and how did it perform? To what
extent are there industry best practices addressing forms of interconnection and diversity and redundancy?
To what extent were they followed?
Effect on 9-1-1 Systems and Services. What could be done to improve the reliability of the 9-1-1
network when faced with storms like the derecho or other threats? Are there actions the FCC should take
to improve the reliability of 9-1-1 services during strong storms like this? What actions should
communications service providers take? Are there actions that communications service providers and/or
PSAPs should take to improve the 9-1-1-restoration process? What, if anything, can the FCC do to better
assist communications service providers and PSAPs in the restoration process?
How was 9-1-1 call completion affected by outages caused by the storm? Is there an estimate of
how many 911 calls could not be completed at all or only through alternate means, such as ten-digit
numbers? To what extent do industry best practices exist that relate to these events, and were these best
practices followed? Were there instances where PSAPs went offline due to failures on their own
premises? To what extent did the storm affect Automatic Number Identification (ANI) and Automatic
Location Identification (ALI)? What were the primary causes of failures to ANI and ALI services? To
what extent were vital 9-1-1 facilities and network elements deployed redundantly by service providers?
For example, were selective routers routinely deployed in a diverse manner? Likewise, were facilities
that carry ALI and ANI information routed in a diverse manner? What should be done to improve the
diverse provisioning of 9-1-1 facilities and elements?7
Effect of 9-1-1 Outages. What impact did the 9-1-1 outages have on the public? For example,
how were consumers affected? How did the outages affect the ability of public safety officials to perform
their duties? How was the public alerted of the 9-1-1 outages and what alternatives were provided? How
effective were these alternatives? To what extent was social media used to spread the word about the
9-1-1 outages and alternatives? What impact did the 9-1-1 outages have on other sectors of the user
community, including businesses and providers of critical services, such as hospitals?
Effect of Communications Outages on Access to 9-1-1 Services. Outages in the 9-1-1 network
itself are only one way that users can be denied access to 9-1-1 services. For example, if the PSAP is
operational and the 9-1-1 network is functioning, users in a local area will still be unable to reach the
PSAP if they lack access to the communications network due to a local outage. To what extent did users
find that the general unavailability of communications service impaired their ability to access 9-1-1
service? In these instances, were multiple methods of reaching the PSAP available, like cell phones or
other types of communications services? How effective were these alternative communications services
in overcoming outages affecting one access platform? What should be done to improve the diversity of
access to 9-1-1 services so that communications outages are less likely to result in an inability to access 9-
Questions Regarding 9-1-1 Resiliency and Reliability GenerallyThe 9-1-1 communications failures experienced as a result of the derecho also give rise to
concerns and questions about the reliability and resiliency of our 9-1-1 communications networks
nationwide, particularly in the event of a severe weather or other type of high-impact natural disaster. We
seek comment on how 9-1-1 communications has fared during other recent natural disaster events. Please
describe any lessons learned from those events, in particular improvements that were recommended to
improve 9-1-1 service reliability and survivability. Commenters should address the impact on
communications relying on the PSTN- and IP-based communications, as well as fixed and mobile
We also seek comment on the most common causes of failure in the 9-1-1 network that result in
the following types of 9-1-1 outages: i) complete isolation of the PSAP; ii) failure to pass ALI and/or
ANI; iii) loss of the ability to re-route traffic to an alternate PSAP or administrative lines. What could be
done to reduce the incidence of outages in each category? What actions, if any, should the FCC take to
address this problem?
In what ways does the practice of deploying redundant facilities or systems used in the 9-1-1
network promote 9-1-1 reliability? How does the service provider ensure that these practices are
followed routinely and remain in place over time, even as changes are made to the networks? What, if
anything, should the FCC do to promote the application of such methods?
How do service providers routinely monitor 9-1-1 facilities and the availability of 9-1-1 service?
How quickly do service providers become aware of 9-1-1 failures of various kinds? Do service providers

Providers of the Importance of Implementing Established 9-1-1 and Enhanced 9-1-1 Best Practices, DA 12-891, rel.
June 6, 2012.
routinely notify PSAPs of 9-1-1 outages? How are they alerted, under what conditions, and how quickly?
What steps does the service provider take routinely to prioritize restoration of 9-1-1 service? What
standard operating procedures and systems does the service provider have in place to facilitate the
detection and restoration of 9-1-1 service after an outage? Are these resources adequate?
PSAPs are typically small operations playing a large role in protecting the safety of the public.
The failure of a few trunks into a PSAP could affect public safety for an entire community, but the failure
of just a few trunks might not attract much attention from a service provider. Do provider alarm systems
provide adequate visibility to relatively small outages that can have a large impact on PSAPs, especially
when demand may spike, such as during or after a major storm? Do providers provide appropriate
urgency to handling such outages?
To what extent is the availability of multiple access platforms (e.g., residential telephone line,
whether legacy or IP-based, cell phone, etc.) to reach networks services creating greater richness of
diversity that would tend to improve 9-1-1 reliability? Stated differently, to what extent does the public
have more than one way to reach 9-1-1 that are not reliant on each other? To what extent are available
access platforms reliant on each other or another common point of failure?
The legacy communications network uses a hierarchical architecture, whereby failures of network
elements located deeper in the network will result in a larger number of customers being denied network
service. For this reason, elements deeper in the network (e.g., switches) were often designed to very high
reliability specifications. To what extent has the legacy infrastructure retained this characteristic?
Today’s networks are quickly migrating to broadband IP technology. To what extent does the migration
to IP-based networks reduce or increase the level of concentration deeper in the network? What is the
resultant impact on communications reliability?
What other steps might service providers take? What actions should PSAPs take? What other
actions, if any, should the Commission take to encourage those steps? What actions should the public and
other institutions like hospitals take, if any? We seek comment on whether the deployment of Next
Generation (NG911) will improve the reliability of 9-1-1 services and, if so, how? Would NG911 make it
easier to have more than one backup PSAP and provide additional redundancy of transmission facilities,
e.g., via satellite or microwave point-to-point links? Did commercial data centers in the affected areas
experience outages and for how long? Would it increase reliability if critical components of the NG911
system are housed or replicated in commercial data centers?
NG911 will create the ability to utilize a “virtual PSAP.” Today’s 9-1-1 system generally
requires a call taker to answer a 9-1-1 call from within the walls of a single physical (“brick and mortar”)
PSAP. In a NG911 network, however, a call taker will be able to answer a 9-1-1 call from virtually any
location. We seek comment on the potential for development of virtual PSAPs. Are current technologies
sufficient to support virtual PSAPs? Are there specific steps that service providers should take to ensure
that they have adequate reliability when implementing NG9-1-1? How would the addition of a 9-1-1 text
capability provide substantial improvement in the ability of consumers to contact PSAPs?
