2023-05-17: High error rate in Git

Customer Impact

Failed git commands like git clone/fetch/push

Current Status

The error spike auto-resolved on its own. GitLab workhorse is failing to connect to all the Gitaly servers which is causing timeouts. We've seen this happen last week around the same time as well in #14074 (closed) and #14087 (closed).

We will continue the investigation in https://gitlab.com/gitlab-com/gl-infra/reliability/-/issues/23740
