[Development] Coin infrastructure changes

[Frederik Gladhorn]

Hello :)

One day late, we're attempting to switch now. For a short while things will 
take more time (we're so to speak warming up the caches right now), but 
hopefully things will be progressing as normal again.

If you see completely weird behavior, we're of course happy to hear about it.

Cheers,
Frederik
