T-Mobile suffered from a huge network outage yesterday, affecting customers across the country.
Reports suddenly spiked to over 60,000 on the outage-tracking site Down Detector where T-Mobile customers are reporting a lack of signal or service from Washington D.C. to Los Angeles and everywhere in between.
Whilst systems eventually returned to normal, it took several hours for the reports of problems to subside.
Here's how the events progressed.
More than 60,000 outage reports
Over on DownDetector, there are currently more than 64,000 reports from users across the country.
It appears reports started flooding in around 1:00 pm Pacific before truly spiking 30 minutes later.
Outage appears National
I'm seeing outage reports from nearly every major city in the United States and multiple states from Florida and California to North Carolina and Washington.
Minnesota, Louisana, and Hawaii are all reporting issues.
THe complaints are all similar, phones are being forced into SOS mode only, though it's not clear if WiFi calling is down as well.
No response from T-Mobile
T-Mobile doesn't appear to have a network status page. I have been checking the official T-Mobile and T-Mobile customer service accounts on Twitter where customers are flooding the accounts with complaints.
However, right now the company's reps are just asking people to DM or saying they're sorry the customer is having problems.
"I’m really glad you reached out and brought this to our attention. I’d be happy to help take a closer look into what’s going on. To make sure your information stays protected, please send me a DM with your contact details and we’ll continue there," is a common response.
I have yet to see acknowledgement of the outage itself.
Megathread on Reddit has thousands of comments
I found a megathread on the T-Mobile subreddit where thousands of comments are reporting issues with their phones.
One thread seems to be that iPhone users are having more issues than Android owners. It's not clear why.
Reports are declining but still in the 10s of thousands
On Down Detector I am seeing reports declining. There are still nearly 40,000 reports which is down from the peak of 64,000.
T-Mobile messaging changes
Over on Twitter, the T-Mobile Help account messaging has changed a bit. There still isn't an official post acknowledging the outage but this is what I'm seeing now.
"Thank you for reaching out. Our teams are actively working the reports of technical challenges impacting some customers. Any service impacts are in the process of being resolved and are our highest priority. We know how critical it is to stay connected, and every available resource is focused on resolving this as quickly as possible."
I have reached out to T-Mobile for a statement and will update if I receive one.
Leveling off
Reports have leveled off to around 20,000 on Down Detector and I am still seeing comments reporting where service is out like Oakland, Maryland and Long Island, New York.
One person did say that T-Mobile engineers are on the problem per a call with customer service. Though they didn't have any other information to share.
T-Mobile finally acknowledges the outage

Over two hours after reports spiked on DD, T-Mobile has finally acknowledged the outage with a post on its T-Mobile Help account.
"Our teams are actively working on the reports of technical challenges impacting some customers. Any service impacts are in the process of being resolved and are our highest priority. We know how critical it is to stay connected and every available resource is focused on resolving this as quickly as possible."
Many people in the comments are saying that the outage has lasted even longer, up to 4 hours for many, and are upset with the company's silence to now.
Reports continue slow decline
Over on Down Detector, reports have been started declining again. It's not the steep drop that occurred a couple hours ago.
After holding level around 20,000, we just hit 16,000 as of 4:30 pm Pacific.
Most comments are still reporting SOS mode across the country but I have seen a couple posts about it being back up in California.
Taking a break but keeping an eye on things
It's getting to the end of the work day here on the West Coast. I'm taking a break to walk the dog and get some dinner going but I'll be keeping an eye on the outage and I'll let you know if anything changes.
