The problem appears to be on the server provider's end. About all we can do from the Zero-K end would be sending them snippy emails. Since they are already working on the problem (as far as we can tell) this does not seem necessary.
The provider's status feed is here: https://twitter.com/ovh_status?ref_src=twsrc%5Egoogle%7Ctwcamp%5Eserp%7Ctwgr%5Eauthor
I'm not sure which of those messages affects us though.
(In theory more money might buy more reliability but in my experience even the servers for AAA games go down from time to time, so I don't really know how much it would help.)
