I’m very happy to hear that — thanks!

I’ll reply to your earlier questions below.

4GB of storage is fine. Currently we have a ~4GB soft limit on 
RAM, going over that would notify us and we’d discuss it with you 
directly.

No.

You can consider them to be on the same local network where the 
machine running your build is. There’s a special 
`.semaphore-cache` directory which you can use to store arbitrary 
files:

Cache hit is not yet 99% but it’s our goal to reach it.
