The important part you should consider is to switch go git. I'd recommend starting to use Github, and if you find that it's down too much, look at alternatives or at hosting a solution yourself.
It works well for us. We just have to pay the price of a VPS and updating the system occasionally.
That said, I have two pushes for two clients this morning that may not make it through in time for the status meetings.
If you have a company full of people, it may still be worthwhile to have a couple of them really learn git, and setup a git server internally.
[Edit: And my pushes made it through anyway. Still happy w/ github]
The big difference is that in the second case you can keep working on your local repo without touching the central repo, at any time add new remotes to your local repo and pull and push from your peers.
If GitHub is down, you just keep working. If your svn server is down, you just pile your local work waiting for it to come back up, the tool will not help you in that case.
Moving from svn to git is a no brainer, even if you keep using it as if it were svn most of the time.
Git has a file protocol so you can also just sync your changes between one another via a network share of your repo. Or SSH or email each other pull requests.
