Today I was surprised with a credit score of -76,988.
The loss was all with Prime Tuples, which went to 214,223 from yesterday's 291,211.
All credit scored between 2021-02-26 and 2021-03-15 is gone.

This appears to be oversight on my end...
Let me explain what is going on. For a long time, the database was always being corrupted after a long write-intensive task (reorganizing, post-processing, etc) for unknown reasons. I always restored from daily backup and forgot about it (and the task that caused it). But this time, i decided to actually fix it.
Obvious solution: the disk could be failing - replaced it and hit the db with test workload. It still corrupted.
Hmm what if the sata host controller is corrupting data? (some of the same model did) But at this point, the uptime of was suffering too much (there are other services running besides boinc), so I moved to spare, weaker, computer (parlon). But I forgot about boinc forums and stats. Doh!
Well the sata controller was not the cause, it still corrupted after connecting the disk via USB to the now-offline computer (saran) and running the test workload.
Now it is running memtest, because it could be caused by DDR3 bit flip.

Maybe you need finances?

They promised donations to help projects in which I take part.

I've written emails to the ODLK and ODLK1 project administrators, but they don't seem to be willing to update the servers.

In addition, they promised to present a good server there, but it can only be hosted in the USA.
