I hope it doesn't come to this, but if it does, I think we should really 
look hard at ShiningPanda instead.

Honestly, my feeling is that if we can't rally up $240/month in funding 
among Cython users then we might as well give up. (And specifically, we 
could ask NumFOCUS first, and possibly share the queue with other open 
source projects on their lists, and possibly ask ShiningPanda for an OSS 
project rebate).

I'm not primarily concerned with uptime, but with the time spent in 
maintaining the systems. The more that can be moved into the cloud the 
better for open source projects, if it means less maintenance, which is 
usually the case; see our move to GitHub.

ShiningPanda also offers features like testing on Windows.
