The well-known online
wiki library gives error 502 soon as an hour. Hopefully, this is only a small and temporary technical problem.
UPD: everything, already wound up, already working. So far, there are no comments and explanations, but as correctly
noted , “On the previous pages, it was already a long time ago that it was possible to understand that“ 502 ... ”with the signature“ nginx ”means a local failure on the server itself - the database broke, the log swelled, there-still happens (and it would be very surprising if it were not “for everyone”, but only for the elect). Well, if there is a server crash, and the server has a host, who, probably, the server is monitoring - he has cards in his hands, our business is not to get under our feet and wait. ”
Dear owners! Thank you very much for your work, excuse us for being obtrusive - we just worry.
