Just copy/pasting an announcement by Ross Golder:
Due to reasons beyond our control, we will shortly be changing the IP addresses for the GNOME subversion and L10N machines. I currently expect we will be doing this at some point on Sunday 16th September 2007. The old IP address should continue to work until 22nd September, by which time the DNS change should have fully propogated.
This change will largely be transparent except for developers using Subversion/SSH, for whom this change will likely cause your subversion client to give an warning. This warning is just to highlight the fact that the IP address has changed and can be ignored.
The new IP address for the subversion server will be 220.127.116.11, and the server’s host key fingerprint is as before:
Apologies for any inconveniences. Please post any questions, comments or follow-ups regarding the change to email@example.com.
Note: Initially, the IP alias for l10n wasn’t working. It is now. Further, the change in this announcement already happened.
