OVH has scheduled a maintenance window for 5:00 EST this evening, hopefully they will be able to pinpoint the fault and get parts replaced at the same time. This will likely be an extended outage as they have more diagnostics than I was able to run, so I would expect somewhere around an hour or two of downtime during this.
I am mildly tempted to go ahead and migrate Lemmy.tf off to my new environment but it would incur even more downtime if I rush things, so it'll have to be sometime later.
Update 7:30PM:
I just received a response on my support case, they did not replace any hardware and claim their own diagnostics tool is buggy. We may be having a rushed VM migration over to a new server in the next few days... which would incur a few hours of hard downtime to migrate over to the new server (and datacenter) and switch DNS. Ideally I'd prefer to have time to plan it out and prep for a seamless cutover but I think a few hours of downtime over the weekend is worth ending the random restarts. I'm open to suggests on ideal times for this to happen.
