I've just started shopping. I had an outage about 2 weeks ago, got put into "safe mode" (about 500K), and it was 4 (!) days later. Now I'm stuck about 650K down (for my 1.5M down), and they think it's fine. My standard is just a notch above the "safe mode"? I never really got them to work on it -- a Verizon tech showed up one day, but didn't know why ...
