FCC to Investigate Nationwide 911 Outage

(The Washington Post) -

Federal authorities said they will investigate a nationwide outage that kept AT&T customers from being able to contact 911 on Wednesday night.

The Federal Communications Commission said its investigation would determine how many people were affected by the outage as well as what caused the issue, which was reported by law enforcement agencies and first responders across the country Wednesday evening and confirmed by AT&T, a Dallas-based telecommunications giant.

“Every call to 911 must go through,” Ajit Pai, the FCC chairman, said in a statement announcing the probe. “So when I first learned of yesterday’s outage, I immediately directed FCC staff to contact AT&T about it and the company’s efforts to restore access to emergency services to the American public.”

Pai said that he had directed FCC staffers “to track down the root cause of this outage.”

AT&T has not said yet what it thinks caused the issue, nor has the company said how it wound up restoring 911 service. In a pair of messages posted on Twitter, AT&T warned of an “issue affecting some calls to 911 for wireless customers” and then, 41 minutes later, said the issue was resolved.

Issue has been resolved that affected some calls to 911 from wireless customers. We apologize to those who were affected.

A spokeswoman for AT&T declined Thursday to respond to a list of questions regarding the breadth of the outage and how many attempted calls did not go through. She provided a statement from the company saying they would give more details to the FCC for its probe.

“We take our 911 obligations to our customers very seriously and will be sharing additional information with the FCC,” the company said in a statement.

The National Emergency Number Association, a nonprofit focused on 911 issues, said reports indicated that some callers trying that number received “fast busy signals” Wednesday.

Law enforcement agencies from Washington to Colorado and from Massachusetts to Texas reported 911 problems on Wednesday. In Washington, a spokesman for the city’s Office of Unified Communications said that D.C. officials began responding to the outage about 9 p.m., about 90 minutes before AT&T said the issue was restored.

However, it was not immediately clear how widespread the issue was. In Colorado, for example, police in Denver and Lakewood, a nearby city, warned of problems with 911; but Aurora, another city in the area, reported that its own tests did not find the problem there.

During the outage, agencies directed people needing emergency help to call or text nonemergency numbers, which meant that locations of people calling were not always immediately known.

Issues involving 911 outages have drawn public attention in recent years. In 2014, the FCC released a report delving into a widespread 911 failure that year impacting more than 11 million people across seven states. In Washington state alone, every single resident appears to have lacked “fully functioning 911 service” for up to six hours, the FCC said.

The outage, which the FCC said “was caused by a software coding error” at a Colorado call-routing facility, ultimately kept more than 6,600 calls from reaching call centers during that six-hour window. It stretched from Florida and the Carolinas to California.

“What is most troubling is that this is not an isolated incident or an act of nature. So-called ‘sunny day’ outages are on the rise,” the report stated. “That’s because, as 911 has evolved into a system that is more technologically advanced, the interaction of new and old systems is introducing fragility into the communications system that is more important in times of dire need.”

Lisa Fowlkes, acting chief of the FCC’s Public Safety and Homeland Security Bureau, which deals with issues including 911 calls and emergency communications, vowed that the agency would figure out the scale of what happened with the outage on Wednesday night.

“The FCC’s public safety professionals are on the case,” Fowlkes said in a statement. “Access to 911 emergency services is essential for all Americans, especially the most vulnerable. We will fully investigate this outage and determine the root cause and its impact.”
