To find out if there's an outage for Comcast TV, Internet or phone service, check Comcast's smartphone apps and website and the menu on your cable box. You can also contact Comcast by text, phone or online chat and check social media for other people's outage reports.
Check the App
If you're having trouble with your Internet connection, you may need to disconnect your smartphone from your home Wi-Fi in order to use your cellphone data plan to connect to Comcast's apps and websites. Of course, data charges from your phone carrier might apply.
Comcast says that it will post information about any known outages to its iPhone and Android "Xfinity My Account" apps. If there's information about an outage, it should appear when you log in to the app, and you'll be able to tap for more information.

Check the Web
You can also check for outage information at Comcast's website. The company reports that it will show outage information as soon as you log in to the site with your smartphone, tablet or computer.
Check Your Box
Certain Comcast cable boxes can also display information about any known outages.
For a newer box running Comcast's X1 Entertainment Operating System, an alert for any outages in your area should show up when you open the "Xfinity My Account" app.
If you have a cable box running another operating system, you can use the menu to check for outages using the following steps.
Press the Menu button on your remote control.
Use the remote's arrow keys to select iTV on the menu screen and press OK on your remote.
Use the remote's arrow keys to select Self Help and press OK on the remote.
Use the remote's arrow keys to select My Services. The screen should display any problems with your Comcast TV, Internet or voice service.
Older cable boxes, including certain Motorola units, may not support the iTV menu option. Instead, look for a menu option detailing the cable-box setup options. The screen displays diagnostic data, including whether your service has been suspended for non-payment and whether there are current degradations in signal strength.
Send Comcast a Text
Text the word OUT to the special number 266278 to get a reply indicating if there are any outages in your area. Your cell phone number must be on file with Comcast for this shortcode to work.
Call or Chat with Comcast
If you're having problems and don't see a reported outage, or you prefer to talk to someone in person, contact Comcast through the company's live online chat portal or by phone at 1-800-COMCAST.
Check Social Media
If you don't see any reports of an outage on Comcast's website or app, but you think there might be a problem the company hasn't caught yet, you can also see what other Comcast customers are saying online.
Searching for "Comcast" on Twitter will often bring up live outage reports from other customers. Comcast users also discuss service problems on the company's official Web forum and in posts on Comcast's Facebook page.
The website Downdetector also collects reports of outages and service problems at Comcast and other telecommunications companies and posts them on an interactive map, so you can check there to see if others in your area are having problems.
