After running a line test, they suggested I bring the modem in, so they could have a look at it, so I did. Nothing wrong with the modem, and the "Internet" light came on in their office.
Sooo... I bring the modem back home, plug it in, STILL no "Internet". I call the ISP back. After being on hold a while, the woman said there was some kind of "outage", scheduled to end at 9:45am tomorrow morning! I thought "Argh... Andrew's NOT gunna be a happy camper when he gets up and finds he can't play his online games!"
So, I go out to retrieve the laundry from the dryer. While folding the laundry, I hear an email arrive. Came into the 'puter room to check, and sure enough, the "Internet" light was on, and pages were again loading.
Just hopefully it'll STAY on for a while...
