Systematic issues in NIA's in-game events for the last 6-8 times every time

in Report a Bug
If I remember it correctly the last 6-8 times NIA's in-game events have had some kind of issues every time: Game actions not counting for Medal, it takes 1-2 hours from event start until actions are counted, etc.
From the latest release notes 2.77.1:
Bug Fixes
• Fixed: The C.O.R.E. renewal time was off by up to 1 hour.
Maybe NIA's "in-game event time" is also off by hour or two ?

This seems to be fixed. Didn't notice any issues with the latest "Courier Meet You Out There Challenge" event start:
Thanks! @NianticThia @NianticBrian
Yes but there was massive lag shortly after the event started.. that to me is a problem...
