Comcast Xfinity internet is down, and outages at Verizon, AT&T, and T-Mobile are also possible [UPDATE]

Comcast Xfinity outages peaked immediately after midnight EST and peaked again around 7 a.m. Illinois, Indiana, Pennsylvania, New Jersey, and New York all experienced outages. This internet outage appears to have impacted TV service in these places as well. UPDATE: Users across the United States are experiencing issues with various mobile internet services and internet providers, almost as if there were a single problem.

Comcast/Xfinity (AS7922) had substantial difficulties as of 8 a.m. Central Time, according to a NetBlocks report. According to NetBlocks status measurements, the areas with the most major outages were Indiana and Illinois, followed by Pennsylvania. However, after the first disruption, service appeared to be restored quickly in New Jersey, New York, and Delaware.

Update: It appears like there is a bigger outage here, as multiple wireless internet providers have reported serious difficulty. Using DownDetector, matching complaints revealed waves of problems with Xfinity, Verizon, Spectrum, AT&T, T-Mobile, iNet, Blazing Hog, FirstNet WiLine, and Metronet.

UPDATE 2: It appears that the various internet and mobile data carriers mentioned (other than Xfinity) were the subjects of the same sort of report-echo as the social networks and popular apps that tend to get some of the blame for issues caused by one internet carrier, as reports of issues with carriers other than Comcast have effectively abated since this article was published. The original article can be found here.

If you look at a reporting site like DownDetector right now, you’ll notice reports of social network troubles growing and declining at the same time, as is typical. When internet providers encounter problems, this happens because it’s not always evident who is to blame for a user’s inability to use a service.

The reports during an outage like this will also show you which services people utilize the most. Gmail, Reddit, Google, YouTube, Blackboard (for schools), Amazon, Zoom, and Starbucks feature near the top of the list. Right now, servers for the titles Destiny and Call of Duty are receiving a flurry of reports.

If you use any Microsoft service, you’re probably experiencing problems right now as well. Azure, Office 365, Outlook, Microsoft Teams, the Microsoft home page, and other Microsoft services are included.

We’re likely witnessing the effects of a single problem in internet provider services in the United States. This is a fantastic example of when you should think about how you’d handle an emergency if the internet were down for a lengthy period — what would you do?
