Everything was (almost) seamless, just a slight downtime.
Firstly, the VM that hosted https://api.moritaka.xyz/
experienced some data degradation; as expected, since it's on a shitty laptop hard drive with no actual parity or redundancy. How exactly it died is unknown; how to prevent it is completely known. While I was already under the hood remaking its VM, I went ahead and did the scheduled changes I wanted to do (and could do right now). I do aspire swapping that dingy drive with a logical solution (two mirrored M.2 SSDs, but the benchmarks seem supbar on another system.
To pretty much everyone else, there should be no changes at all. Maybe there'll be added stability; maybe not. Every service is now under it's own internal network with a VM as a "firewall", although I already had one, so :shrug:.
Services may be sluggish as the nitty gritty gets set in place, and all sorts of caching I don't know about do their thing.
