Here near Boston I've been on the cable tri-fecta for over 6 months. Even when the power goes out the phone is still working. Not a day's outage yet.
Wish I could have written the same for my DSL connection. It seems they would offline entire states with what appears to be "human error."
I've had the "bundle" installed(8am-12pm window--arrived@2:30pm) for about two weeks. Land line is now undependable. All three services were also down a day after install. One Tech sat in his truck for hours while waiting for correct equipment to arrive. I've literally waited days(combined time)for repairmen. Wait for it to be around a while--don't get it now. It's 2pmEST now and I called VZ @ 11:55am to see where my 8-12 window service appointment person is. I haven't received a call back or any one at my door....yet again. Sadly I don't think Comcast is any better.
