503 errors rolled back progress?

Twice today Duolingo has had 503 error messages, and just now I noticed it came back after a couple of minutes and my last 2 levels of a skill were reset. Is the site under attack or something? I don't mind being rolled back to restore the site, but it would be nice to have some kind of update if it's a fixed or ongoing problem.

this has been happening to me since I upgraded to plus a week ago, but without the 503 error. I would have lost easily 30 lessons in the last week.
