Restar home service

First. Check their site for official info on any possible local outages here;

https://www.xfinity.com/support/status 

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
