I use AT&T DSL. This week, that's meant NOT having an Internet connection. Why? Nobody knows, but it's certainly adversely affecting my ability to do my job. Case in point: I'm posting this from my iPad via Verizon.
Please bear with me. So far, AT&T has met this challenge by refusing to accept phone calls, providing no explanation or estimate for when it'll be fixed and "Apologizing for the inconvenience". For days, now.
