Unable to pull from my repositories, permission denied

gitlab.com started to give following error today for all of my repositories on gitlab.com. I checked my public key is added and permissions are valid. Web UI works fine, but I’m not able to use git to interact with my repositories:

$ git pull
Permission denied (publickey).
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

Is this a known gitlab.com issue which happens now or does it affect only my account?
