He talked about "here in germany". "germany" is a nonexistant entity
in BGP and global routing. You cannot talk about observation of
connectivity problems with location specification in terms of
"countries".

I did the traces myself, with dest port 53. I'm not stupid (at least
not that much). Given that DREN is the operator of the root server, and
the trace ends _within_ DREN, it's highly likely that the problem is
inside DREN. Anyway, even that can be filtered by a firewall with
protocol inspection, and the actual problem can be on the path back.
This is why I said "seems to be", not "is".
