[BLOCKING] 500 on the api / 503 error when accessing a project

Description of the problem

500 on the api / 503 error when accessing my project

Which Group/Project (with full path) is experiencing the issue?

https://gitlab.com/weome/backend-cloud-test (this is a private project/group)

Approximate date/time when the error occurred.

11 September 2019

Describe what you were doing right before the issue occurred.

First, the project was bugged, I got a 404 on the repository page and it could not fetch the pipelines but everything else was working on the website. So I tried to change the path to backend-cloud-test (was backend-cloud before) and now there is a 503 error on every page. I also have a 500 internal error where this project is present in any api request.

This is a copy of https://gitlab.com/gitlab-com/support-forum/issues/4800 because I think this is a severe issue that is blocking the user.
