I am planning to stop the test servers for a while or let them run until they are broken, I guess this is happening now.
Because the usage is very low on the test servers, it isn't a priority to run them flawlessly as we used to.
The code is getting very old, every SVN update (or the new GIT) it generates a hundred conflicts that need manually resolving. Those could be because of the anti-mob-spam system and other anti-abuse features we implemented to make it work as a test server initially. So we do need some time to rework the test servers if we ever give them a second look. Right now nothing much can be done, you can assume they are out of service. Sorry to break the news to you.
