Odin not updating tiles?

[nrenner]

There are multiple reports in the German forum that changes are not appearing on the map.

First examples are starting Friday, some later changes:

There is no replication lag so it should be fine - most likely you're just seeing cached tiles that haven't invalidated. The invalidation algorithm is only heuristic and some type of change will not cause invalidation.

Unless you can identify a systemic problem somehow it's not really practical to investigate individual tiles like this - the work involved is significant and we have limited manpower.

All these appear to be fine after a rerender is force so it's just tiles that didn't get invalidated for some reason.

I managed to identify an issue in the expiry script caused by the update to Ubuntu 20.04 on the tile servers that I have fixed in openstreetmap/chef@fb3022d.

Pending changes are now processing, but some will have been lost as they expire from the queue after a while - it will self correct when the style is next changed or if the same area is touched again.

Thanks for the fix and explanation, I passed it on.
