I'm dropping this back into needs refinement as I couldn't find the instrumentation spec for it, if one exists. @Madalina I've chatted with @phuedx from Data Platform Engineering about the best next steps/best practices for gathering this data and we concluded that one of the following two would be ideal:

Not sure if there's any action on PSI's end and it seems to have self-resolved:

Done

I don't think there's anything actionable here. I checked caching in general and it's working as expected. The function getAndUpdateExternalWikiPermissions is also working as expected, as it doesn't check if it should update the cache before doing so it'll always make every call it's asked to. This did cause issues and was removed in I6a538af556efcbd8db1e696f89621d5b670bca6f.

I don't think this is resolved? The issue wasn't actually fixed during the election

[Vue warn]: There is already an app instance mounted on the host container.

I can confirm that while performing a CU on that temporary account does reveal the IP (account creation's IP, I suppose), no edits are reported from that IP.

T407651: IPs can't be revealed for some temporary accounts on itwiki may be another report? However the revision also isn't available to cu_changes which is a larger scope than this ticket mentions.

I investigated this and it seems like the problem is actually upstream and possibly the same as T364245: English Wikipedia recentchanges table missing some revisions. IP reveal is behaving as expected - it can't find an IP for the revision because one was never written into cu_changes (The revision isn't in recentchanges as well). As a result, no information about this revision would be available to CU either. I'm going to close this, as any fix should be made in ^, but please re-open if you think there's something we can do for IP Reveal that would help.

The only users who this wouldn't apply to are users like stewards, but it is harder to define when a user has the -no-preference right on every wiki (given some global groups are disabled on some wikis).
