Use a cell phone internet service, a public WiFi hotspot, or a neighbor's internet if you need to in order to check it.

Or you can use their Xfinity App: https://www.xfinity.com/apps 

Hi there, @user_j5liee! Sorry to hear about the downtime. As @EG pointed out, browsing over to https://www.xfinity.com/support/status or logging in to the XFINITY App are great ways to quickly find out if there is a service issue. You can also troubleshoot any problems you have with the XFINITY App. More details here : https://www.xfinity.com/support/articles/check-service-outage and here : https://www.xfinity.com/support/articles/internet-connectivity-troubleshooting. Are you still offline at this time?

Were you able to find any outage info on that site or in the app ?
