I don't know if you follow the news, but there was a huge bomb set off in Nashville Christmas morning in front of the AT & T building. It took down all the cellular phone service and internet service for AT & T customers in the middle TN area and parts of Southern KY and northern AL. I just got internet back last evening and still don't have cell phone service.
Luckily I have DISH satellite TV, so I knew what was going on. The folks with DIRECT TV lost TV service too.
Law enforcement lost their 911 centers, too. It was a weird couple of days. Most of us are just so dependent on our cell phones now!
My family could not get in touch with me on Christmas and were so worried. They said when they called my number it wouldn't even ring, and no message at all came on saying the lines were down.
I am glad to be partially reconnected to the world now. Let's hope that this was just an isolated nut, and not something else.
