Investigate why data was missing from mediawiki events around January 3rd
Closed, ResolvedPublic

Description

The parent task, T185019, shows that there was missing data for January 3rd through January 6th, 2018. We should look into that while we have fresh monitoring data. Either the reportupdater job that ran those reports was broken for a few days or the data was actually missing and not consumed.

I think likely what happened is mirror maker was late. I'm going to close this task for now, as the parent was closed. We need a more resilient MirrorMaker anyway, tbd T189464
