(Update May 30, 2026 12:00 am EST): T-Mobile has now issued a statement on the T-Fiber outage that caused widespread problems in its former Lumos service areas, with the issue lasting for more than 36 hours before service appeared to stabilise. The problem began around 1:00 AM on May 28, and customers reported that some sites would not load at all even though their home equipment still showed a normal connection.

As reported by The Mobile Report, T-Mobile said the disruption was tied to a “network equipment issue.” The carrier said service had been restored for many customers, but admitted that some users were still seeing interruptions while repair work remained ongoing. T-Mobile also acknowledged that some customers received a message saying service had already been restored, and apologised for the confusion.

According to the report, T-Fiber emails sent during the outage said hardware had been replaced and further repairs were in progress. A later message told customers to reboot their equipment, but some users said that update was premature because their service was still not fully working.

The latest update said things seemed stable by 8:15 PM on May 29. That means the outage ran for well over 36 hours, and even near the end some users were still dealing with slow-loading or unreachable websites before service appeared to recover.

If your home internet has been acting up, you may not be the only one dealing with it. A wave of T-Mobile Fiber customers appears to have run into service problems, with user reports pointing to a broader outage rather than isolated issues.

As reported by Android Authority, complaints started showing up at around 1:00 AM ET and climbed sharply through the morning. The report says the issue peaked at about 8:00 AM ET, when Downdetector logged more than 850 reports.

The same report says the outage looked to be concentrated mainly on the East Coast, based on Downdetector’s heat map. While the number of complaints later dropped, hundreds of reports were still coming in, which suggested the issue had not been fully fixed at the time of writing.

For customers, the main takeaway is simple: if your T-Mobile Fiber connection went down overnight or this morning, it may be part of a wider problem. The report said it would continue watching the situation and update its story once T-Mobile’s fiber network is fully back online.
