I have seen about the same here. Changed from SF on Monday of last week. Modem was here on Tuesday. Email arrived late Tuesday with setup info but no IP addresses. Said would be a couple days and I still have not heard from them.
Speed is slower than my SF connection and I can see the CO from my house until the leaves get back on the trees.
Routing on cogent seems real strange as it takes 21 hops to get to my office server 20 miles away. It was half that with SF.
Only one evening support call so far and no one returned the call, I finally figured it out myself as I was on an old bridge connection and a home run that was wired for the outside pair, the Speed Streams use the inside pair and not the outside pair so I scratched my head over than one for awhile.
I operate a small business so I do know what it is like to get slammed all of a sudden. I think they are trying as best they can to deal with this new influx of customers and I am willing to give them some time. I just could not excuse SF for their lack of care for the customer after all of these years. At least I can leave a message at AtlNex even if it is not returned!
