Thank you for researching this, MDS. My connection at work is fine, so I'm getting my TechIMO fix for now. I'll try pinging AT&T's server when I get home.
I'm having the same problem from my home connection. I can access techimo from university, however, any and all attempts to connect from home have failed.
I have tried searching and trace routing among other things including talking with att tech which now says the issue has to do with the host. Who knows if it does or not as from the outside no one yet has had one single response to emails or PM's sent with the exception of the one I sent Scott the day after this all started in which he replied "TechIMO is fine" and provided a link to techimo that doesn't load from here. Also doing traceroutes always traces through theplanet host for RR and techIMO which has me confused to the fact of being hosted by pair unless it is a pair network. The pages here at RR load so slow to the point that it is almost not worth visiting and I'm on a 1/2 T1 cable connection. I just wish to know where the problem lies and what will it take to resolve the issue whether it be a host issue or a routing issue out of reach by the host. My ISP has no issues and from there tech support site can reach techimo without an issue but they are in AZ not Kansas. Even though I'm in Kansas there are at least 12 others that I know of having the same issue with no clue what to try next and all different ISP's, states, and countries in some cases.
