Interesting. I just got through manual update vps 1211120-0, altough it seems just as sheer luck actually, because if I try manual update again, it doesn't say, it's up to date, but throws 404 error yet again
Edit: Now it says my vps is up to date. Seems like servers are getting up or are up again
Edit2: Some servers seems getting it up, because it throws randomly the error, but some are showing normal behavior
