It seems that there's something wrong with the Gym. Attempting to create a new training results in:

"Ooops! Something has broken down in Codeforces. Do not panic, you can try to reload the page or return Home. Anyway we will carefully read megabytes of logs, analyze stacktraces and fix the problem."

with a "All your bug are belong to me" image.

I thought I could repurpose one of my existing contests, but that seems impossible as well — any FTP link of my existing gym contests gives "This site can’t be reached".

I'd appreciate any fix/workaround as I was hoping to set up a quick practice contest for friends of mine today.

Bump: Problem still persists. If for some reason this is happening only for me, I would appreciate any comment indicating that.
