Major communication companies operating in the US saw outages on Monday, as users reported dead signals from several regions across the country, according to DownDetector. Among the affected carriers are T-Mobile, Verizon and AT&T, with fault reports coming from Los Angeles, Miami, Chicago and several other metropolitan areas in the US.
T-Mobile's president of technology, Neville Ray, confirmed the outages in Twitter, saying that the company's engineers are working to resolve a "voice and data issue" that affected T-Mobile customers across the country.
Following cell phone carrier outages, popular social networks and messengers such as Instagram, Facebook and Twitch experienced issues as well, shown by DownDetector.
A Verizon spokesperson, however, denied the reports of issues with the carrier, saying that the site "is falsely reporting Verizon network issues" and assumed that it might be a mistake of crowd-sourced data aggregation.
"These types of sites do not evaluate and confirm the crowd-sourced data that they receive, they simply aggregate it and report it. The result can be faulty reports of network performance interruptions causing wide-spread miscommunication for wireless users", a Verizon representative said, cited by ABC 7.
Concerned by the outage, Twitter users reported problems with Wi-Fi as well, while some suggested that the issues may have been caused by a DDoS attack.
