Neither this version nor the subsequent 1.35.0-wmf.24 can proceed until

Thanks to the many folks who have contributed debugging on T247562 so

Hello,
Eventually we have found the root cause of the issue. The local cache
was being invalidated when different wikis tried to use it which caused
MediaWiki processes to fetch a large key from the same memcached server
and overloading it.
The hotfix is deployed. I will push 1.35.0-wmf.23 to all wikis this
afternoon at or slightly after 13:00 UTC.
