I have used codesearch to search for the config of codesearch with things like https://codesearch.wmcloud.org/search/?q=codesearch&files=&excludeF… I did find the puppet module codesearch and a hound config file in there. But somehow I have not found yet where the "gerrit-replica" URL s configured. Do you see it? Could that be in Horizon Hiera instead of the repos maybe?

Thank you Amir! Also here: https://gerrit.wikimedia.org/r/c/labs/codesearch/+/919925 Sorry for duplicate work, merge / abandon either at will from my side. But I used commit message for reasoning and needed a ticket, so linked to new: https://phabricator.wikimedia.org/T336710 Just today in our team meeting it came up and that we should create a dedicated ticket for it. So the patch would either be temporary or simply never be reverted, even after the maintenance.

Personally I think so, yes. We can make a list of users and discuss on https://phabricator.wikimedia.org/T336710 I also don't know yet which of the users is causing the highest load compared to others.
