An update, now it seems to be working.

dig -x 62.142.217.200 from non-local network returns correct answer. 
Don't know if the upstream provider did something, ttl expired or something.

Anyway we also have 62.142.217.64/27 IP network (you know what I mean) 
which should be delegated to our servers, but that still doesn't work. 
But it's probably a delegation problem.
