Repository and Wiki suddenly disappeared

Problem

I have a private project at https://gitlab.com/dosuken123/tfg. I could correctly look up the repository and wiki page until last Friday(18, Jan), however, GitLab shows the following errors and an empty page from today (21, Jan).

As you can see, all data seems gone. I have not changed anything on this project lately so that my first impression is that something went wrong on production database or file storage which persists repositories. Weirdly, my other projects are still existing and the data including wiki seems intact.

Proposal

TBD
