Great news. Thanks so much for working on this. ;)

In the old cloud some of the builders were bigger, should we bump
these up some when we move to production?

Yeah, easiest to just leave this as is. We could proxy to them via the
master, but it would be a hassle to get all working right.

We could, but I think all the sysadmin-main folks that are interested
are already in sysadmin-jenkins and/or we could add them easily.

Do we have any SVN projects in the old cloud?

Yep. :(

Easy to do anytime. 

Thanks again for working on it.
