About Xfinity (Comcast) outages
Cable internet is shared infrastructure. Customers on the same node share upstream capacity, so a fault affects a specific set of streets rather than a city, and two people a mile apart can have completely different experiences during the same incident.
The symptoms are distinctive: A modem with a blinking or solid orange light has lost the downstream or upstream channel, while a solid white light with no internet points at authentication or a DNS problem. Xfinity's own DNS resolvers have been the cause of several apparent "internet is down" events where connectivity was fine and only name resolution was failing - Switching a device to a public resolver confirms this in seconds. Xfinity WiFi hotspots and Xfinity Mobile are separate products. Comcast provides an address-level outage map in its app and website, which is more accurate than any third-party view for this provider.
What to do if Xfinity (Comcast) is not working for you
Is it them or you?
Our last check reached xfinity.com normally, from a different network, resolver and route than yours. If it is broken for you, the fault is most likely local or too narrow for a single probe to see. Run the check again now to confirm.
The first thing worth trying
Switch between Wi-Fi and mobile data first. This single test separates a provider outage from everything else, and it takes five seconds.
How internet & mobile services typically fail
Everything fails together, including sites that are certainly fine. Pages that are already cached still load, which is misleading. Mobile data working while Wi-Fi does not, or the reverse, is the clearest possible signal. The rest of the steps, and why this category breaks the way it does, are on our internet & mobile status page, with more background in changing your DNS to 8.8.8.8 or 1.1.1.1.
