Monday afternoon major wireless carriers had outages that lasted hours in Colorado and throughout the rest of the United States Monday.

Sprint, AT&T, U.S. Cellular, and Verizon customers experienced outages nearly an hour after T-Mobile customers, according to Down Detector.

T-Mobile customers couldn't make calls or texts during the outages. Verizon denied outages stating that Down Detector was "falsely reporting Verizon network issues".

According to service-tracker Down Detector, T-Mobile outages started at 12:42 p.m. ET. The outages continued and by 2 p.m., 110,822 users were out of service.

This problem continued through the evening, but by 9:30 p.m. ET that number had drastically dropped to roughly 16,500 T-Mobile customers left without service, Down Detector said.

Some customers still experiencing outages with T-mobile nearly 24 hours after the problem started and reported the outages to Down Detector.


According to TheDenverChannel, this is what Verizon's Communications Manager David Weissmann sent E.W. Scripps regarding the outages:

"Verizon’s network is performing well," Weissmann stated. "We’re aware that another carrier is having network issues. Calls to and from that carrier may receive an error message. We understand Down Detector is falsely reporting Verizon network issues. Sites such as Downdetector.com utilize limited crowdsourced data drawn from sample social posts which are often statistically insignificant or factually incorrect. A lot of factors can contribute to a false report on a third-party website … a faulty device, network traffic that slows but doesn’t inhibit connections, commercial RF blockers, human error, network issues impacting other carriers, and more. 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."
