to clear up the confusion.
specifically
photo.net is running on a sun e450 at the focal commuication colo facility in cambridge.
philip.greenspun.com is being served off that box. As a result of his lawsuit I think he had to move it along with photo.net out of aD at least that was what I was asked to do by aD and its counsel. I didn't have to move philip.greenspun.com but it was easy so I did it since it has always been on the same box and I was feeling quite generous.
philip.greenspun.com is behind a firewall and for some reason the firewall settings that were working for a long time suddently stopped working. When I looked at the file I corrected the strange entry.
The keepalive software on the same box thought that the server was fine but it was not.
I am not sure why philg doesn't have uptime running for his machien. Or maybe it is because his company doesn't provide such services anymore.
