Just to add my voice: experienced the same right now - same repository was working fine yesterday (about 12 hours ago). Is this perhaps related to planned maintenance / downtime scheduled for this weekend?
Firstly, we apologize for the delayed response. Over the weekend we had a known issue with storage, however no data has been lost. Normally this would be handled automatically but due to unforeseen circumstances it was not. This issue should now be fixed. If you have any further problems relating to this, please feel free to contact email@example.com.
