Until a few months ago, we hosted our svn repository on berlios.de . It went down every few weeks, so I don't recommend them. We started using them when sourceforge only had cvs. Nowadays sf.net supports svn, so you might look into that.

Somewhat recently, we switched to git and started hosting ourselves, but you might look into code.google.com .

If you don't actually want your code to be public, just get some free online storage. Do you really need more than 5GB?
