s6 master failure
Closed, ResolvedPublic

Description

Tracking task for followup associated with the 2022-10-15 incident in which the db1131, the s6 master, suddenly went offline, we suspect due to a bad DIMM. This rendered frwiki, jpwiki, ruwiki, and wikitech read-only for 24 minutes (plus 1-2 additional minutes during a master switchover). Incident report in progress, will post the link here shortly.

After DIMM replacement, it looks good now. I will slowly start repooling it now.

Now that we have the incident report, can this be closed?
