After months of absence, Typosphere has returned from the dead!
We migrated off of Planet Argon and onto DreamHost, where we should have more control. We also upgraded to Trac 0.10.3 and turned off anonymous editing (users now have to register to file a ticket). This should (hopefully) prevent the issue that lead to Typosphere dying in the first place.
One important thing to note is that as part of this process, we also moved the subversion repository. Unfortunately, the old repository was hosted as an svn:// URI using the typosphere.org domain, which meant there was no way to preserve this URI (since we can’t run long-lived background daemons on DreamHost). The new URI uses http and a new subdomain, so if necessary we can move the repository without moving the website.
The new repository URL is http://svn.typosphere.org/typo/trunk.
