You probably missed the email announcing downtime: Today, starting at 11:00 UTC, the packages implementing the virtualization engine on baron.haiku-os.org will undergo a security-related update. The process will involve a downtime of all virtual machines running on baron, so both the subversion server (svn.haiku-os.org) and our trac installation (dev.haiku-os.org) will be affected. --Daniel Devine
