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

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 

Hello, @user_9rwht0 thank you for reaching out over Xfinity Forums. Working from home myself I completely understand the importance of having your home network up and running. When power is restored to residential locations, our area equipment may not have had power returned or the equipment yet. I see one of our awesome Forum experts @EG provided some helpful information to check from a mobile device to see if there are still any reported service issues in the area.

Please let me know if you're still experiencing the modem blinking orange/no connection concern as I'd like to investigate further.
