Roger wrote a good blog post about strategies for getting more bridge
(you may have seen this already, it was written three months ago).

Have you heard about the Torouter project? We are currently working on
two versions; the DreamPlug for technical users who don't mind doing
some hacking on their own, and the Excito B3 for non-tech users. We
have documented the project here:

this is something you'd like to help with?

You could also just change the IP address of the Tor relay (probably
easier to do if it's a VPS than if you have it at home).
