API not responsive

Some calls to the API have extremely slow response times currently and some return 500.

Getting the list of commits for a gitlab projects lasts for minutes with java-gitlab-api takies minutes and ends up with:

“org.gitlab.api.GitlabAPIException: GitLab is not responding”

Also, from time to time, 500 are returned directly from the GitLab API. Some time ago I was getting this:

The following GET is sometimes returning 500:


I’m using the same lib as always to communicate with the API (the official java-gitlab-api). I have not changed anything in the code on my side recently. The problem has started occurring today.

Response body:

] with root cause

I think it’s not just the API issue but just that gitlab.com is little sluggish even from the web browser.

I got reply on twitter that they had problems with the API and they have ended up switching it off.

We had some issues with our redis cluster yesterday which resulted in the site going unavailable yesterday and slow response times today. You can read about it in the following two issues:
