Makes me think twice about changing my Internet from Earthlink (provided by TWC) to a faster offering from TWC. It works now and I don't think I've ever had an outage in the almost 10 years I've had it in 2 separate houses. Only problem is it's slow as dirt. They advertise 15/3 but I rarely get over 380Kbps upstream which makes working from home all but impossible for me. I'd love to get 30 or 50Mbps down, but I'm afraid of what might happen if I switch...
