> I wonder if it’s possible to detect solar flares in these logs. Need to find a good data source for them. Are there any other events generating lots of radiation that may affect servers?

Cosmic ray showers [1] potentially. My prediction is that there should be "clusters" of bit errors every few minutes or so (given sufficient amount of servers...).

I was talking to a sysadmin at a local company running a few thousand servers about getting their ECC error logs in order to look for these, but scraping them apparently wasn't trivially managable for them.
