Well, if it continues being too disrupting, there is still the possibility to move the repository to codeblocks.org. This should not be any considerable burden to the server, nor take more than a few mins.
The publicly accessible repo could stay at BerliOS and be synced with the original.
This will of course not solve the issue for a non-developer trying to check out or update, but alas... that's just bad luck. It will solve the issue for the development team, however (... and those are who really need to be able to access the repository daily).
