Adding @Addshore and @Ladsgroup as they have lots of cool dashboards (that I
am unable to find) where they maybe can check in a more granular way what is
hitting the hosts.
I have checked all the s8 hosts and this seems to happen on every slave so it
doesn't look related to an specific traffic (api, recentchanges etc).
Checking cronjobs on `mwmaint2001` I can see this one starting at around that
time (however it looks like it runs every 3 minutes anyways):
/usr/local/bin/mwscript
extensions/Wikibase/repo/maintenance/dispatchChanges.php --wiki wikidatawiki
If it happens always around that time my guess would be some batch job or a
bot?
If needed, I could capture some real query logs around the time it normally
happens, I can try to capture an interval of 2-3 minutes (more might be
difficult as the log might be huge). Before doing this I will wait for
@Ladsgroup and @Addshore to see if they can find something on their logs
