No, it’s not just you. Comcast has been down for a swathe of users around the United States today.
At 12:30pm ET today, Comcast took the time to post that they were aware of the internet and television outages. It was at that time that they wrote that their “engineers have been working on this and services are starting to be restored.”
The most recent update, coming at 1:22pm ET, says that the “temporary network interruption” has been repaired. Engineers are working on getting service up everywhere, and most have already been restored.
A recent check on Twitter and Facebook, though, still sees hundreds and hundreds of users reporting the outage every second. Heck, the map you see at the head of this post is a live snapshot taken at 1:40pm ET.
Services are on their way to being restored.
