T-Mobile USA agreed to settle a US investigation for $ 19.5 million (approximately Rs 145 billion) after a massive outage in 2020 resulted in more than 20,000 failed 911 calls.

The settlement was triggered by an investigation by the Federal Communications Commission into a more than 12-hour outage in June 2020, which led to congestion in the networks of the No. 3 mobile operator T-Mobile and “the complete failure of more than 23,000 911- Calling “caused.

As part of the approval decree with the FCC, T-Mobile has also agreed to enter into new commitments to improve emergency call failure reports.

An October 2020 FCC report found that T-Mobile’s outage was affecting call and text messaging services nationwide and access to data services in some areas. It resulted in a total of at least 250 million calls to fail.

The FCC estimated that “over 250 million calls … from subscribers of other service providers to T-Mobile subscribers failed due to the outage” and “at least 41 percent of all calls that attempted to use T-Mobile’s network during the outage use, do not complete successfully. “

T-Mobile announced Tuesday that it has “built robustness into our emergency systems to ensure that our 911 elements are available when they are needed. After this outage, we immediately took additional steps to further improve our network to prevent such events “in the future.”

Then-FCC Chairman Ajit Pai said the FCC employee report showed the company had failed to follow proven network reliability best practices that could potentially have prevented or mitigated the outage.

According to the FCC report, the outage was “caused by a device failure and then exacerbated by a network routing misconfiguration that occurred when T-Mobile rolled out a new router on its network.”

T-Mobile previously said its network saw an 18 percent reduction in calls completed during the outage, but the report confirmed the network congestion “many of its subscribers likely had to make 2-3 call attempts before successfully connecting”.
