Fantastic news! Let's hope they've gone for HTTPS this time. I always found it unnerving when downloading something as critical as firmware from the old server.

I think it would be a good idea to create a list on the wiki of all firmware images and their MD5/SHA checksums in case Microsoft ever decide they want to kill this service. This wiki page should probably be locked to the council for editing to prevent sabotage from untrusted sources. Maybe the council could also download a copy of all of the images too for contingency. I know that there could be issues with the legality of redistribution but that can easily be resolved by anonymous upload.
