Group and all projects have disappeared!

I’ve been using https://gitlab.com/NANO-MASTER/ successfully for a few projects over the last couple of months. Today I try to commit and push some changes to one and I get the following error through my client application (Tortoise Git on Windows):

“fatal: repository ‘https://gitlab.com/NANO-MASTER/NDT_4000_Chile.git/’ not found”

I logged into GitLab to see what’s going on and the whole group (along with all projects) is missing (404 message)! Our GitLab admin. is out of pocket for a few days (International Travel) so I can’t ask him what happened. Can someone tell me? Maybe we ran into some account limits? Nothing I knew about…

Thanks for any info.!
