Looking deeper into this data, a strange pattern was recognized. The events don't seem to be randomly distributed as one would expect, but there seem to be some patterns. In particular, it is notable that a lot of events are happening just in the minute after 22:00 UTC. This seems to be a recurring pattern on many, but not all, days. It is unclear what causes this. - Cache purges shouldn't happen based on the time of day - Maybe some scripts are requesting a lot of data at 22:00 UTC which leads slower responses? - Are we doing some daily dumps or something at 22:00 UTC?
