I lost my internet

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 

Thanks for reaching out @user_kimcee! I’m really sorry you’re experiencing a complete loss of service. I know how stressful it is when you have no internet at all, and I’m here to help get this moving in the right direction.

I see our Expert @EG shared some pretty helpful links. Have you had a chance to see if there is an interruption occurring in your area?
