On Thursday, a large number of users of the American mobile operator AT&T encountered problems when trying to make calls, send messages and contact emergency services. Communication problems are observed in major US cities, including San Francisco.
According to Downdetector, at around 8:15 a.m. ET (3:15 p.m. Kyiv time), more than 73 thousand incidents were reported, and the outage has been going on for at least 5 hours.
AT&T said some of its customers have experienced outages and it is “urgently working” to restore service.
“We encourage the use of Wi-Fi telephony until service is restored,” — the message says.
The outage affected people's ability to contact emergency services by dialing 911. Fire departments and police departments issued statements to that effect.
Moreover, users of all major operators in the United States encountered problems with cellular communications. Verizon, T-Mobile and UScellular customers are also experiencing problems, according to Downdetector. Therefore, the problem is global in nature and not limited to one AT&T operator.
