Damn. The last local ISP in Pittsburgh, which has provided us excellent service, is going away. (I hadn't realized it had gotten quite that bad.) Our choices are Verizon (DSL) and Comcast (cable), so I've just submitted the order with Verizon. This should be a simple transfer (our ISP was reselling Verizon), but they have no apparent process for simple transfers, so we'll see. (No, not going to do Comcast, and not interested in switching technologies until the day Verizon deigns to offer FiOS in our neighborhood.)
With Nidhog (current ISP), service has been excellent, I had the owner's cell-phone number, and the very few problems were dealt with quickly and easily (even the ones that weren't really theirs to fix). Verizon claims 24/7 support but they mean online chat, which has obvious limitations. Getting a phone number at all was harder than it should have been, and I don't yet know the hours when it's staffed. (Not at 10PM on a Saturday.)
Edit: This wasn't clear from the mail I got on Friday, but tonight I learned that Nidhog is not going away completely. They are just ceasing to offer DSL. (I'd love to know what happened there...) If FiOS were available to my address I could buy it from Nidhog (so when it is I will, should it ever be).
