Desolation (Desolation.org) is currently hosted in the Pittock Building in Portland, Oregon. Squid and Armrha are responsible for the hosting and maintenance, with Rynthas also having remote access to the machine.
The server used to be hosted in the Westin Building in Seattle where Rynthas worked. It was an fugly old 2U case, and an old machine. In the picture to the right, you can see the black server on the lower right. (Hint: it’s the one with desolation.org printed next to it.)
