DNS is resolving other addresses fine so does not seem to be a dns issue.

How can I resolve this?

This is actually a bug in Confluence 3.5.4 - upgrading to Confluence 3.5.5 will fix it.

https://jira.atlassian.com/browse/CONF-22528

The bug is now more crucial now that svn.atlassian.com doesn't exist any more 

[Hannes Haataja]

Installing the patch fixed the problem and Confluence started normally! Thanks a lot!

Atlassian does not support Subversion repositories anymore.   They moved to Git.  So, svn.atlassian.com does not exist.   You can try faking out that uri in your local host file and see if you can get your system back up.  I would point it back to own machine.

If the gets you up, I would try to find where svn.atlassian.com is configured/used and remove it.

[Hannes Haataja]

Thanks for the info! I tried setting up the fake url to localhost but apparently the address has to be valid as i got a 'java.net.ConnectException: Connection refused' instead.

[Norman Abramovitz]

Hmm, that's too bad. I would continue faking things up like installing a dummy subversion server on a machine and then pointing svn.atlassian.com to that web services. You could also try looking at your configuration and database tables to see if can disable things as well. Backup before making changes in case things goes terribly wrong. Atlassian support might be able to help, but
