If you couldn’t reach your favorite web sites today at about 12:30 p.m. ET, it wasn’t just you.
Comcast Xfinity customers nationwide took to Twitter with complaints about complain about outages, while Downdetector’s graphs displayed the same spike in complaints from almost every site it monitors, which then began to retreat to normal levels. Whew!
We asked a handful of major broadband providers if they could shed some light on what happened. Comcast got back to us this evening with the following statement:
We identified two, separate and unrelated fiber cuts to our network backbone providers. Our engineers worked to address the issue immediately and services are now being restored to business and residential internet, video and voice customers. We again apologize to anyone who was impacted.
However, major backbone provider CenturyLink, which owns Level 3, responded to us saying it hadn’t had any issues and that its lines were not compromised — rumors had been circulating to the contrary. So it still remains unclear as to who those affected backbone providers were.
AT&T and Verizon spokesmen said their companies were not aware of any impact on their networks.
We’d known about the fiber-line cut since about 2:25, when Joan Gralla from Newsday tweeted out that “Comcast is experiencing a National outage due to 2 fiber line cuts. One between NYC & Chicago, the second between Ashburn & South Carolina.”
Because Comcast supplies internet backbone to a lot of places, it took ’em all out.
Just a few minutes later, all of Comcast’s official central and regional accounts tweeted out “One of Comcast’s large backbone network partners had a fiber cut that we believe is also impacting other providers. It is currently affecting our business and residential internet, video and voice customers. We apologize & are working to get services restored as soon as possible”
This story was originally published at 1:52 p.m. ET Friday; it has since been reorganized and rewritten for clarity and to add the comment Comcast emailed to us at about 5 p.m. ET.
