I could see my websites on my cell phone using the ATT data network. Proof they were up and running.
Down time was between 8:00 AM to about 3:00 or 4:00 PM. (8 hours) I had no idea how to fix it other than wait. It has (obviously) returned. I am using the link now.
COMCAST! (or your routing service) Don't scare me like that!! Ha!
