resolving .org - connection timed out; no servers could be reached

[Erik Dobák]

as i wrote other TLDs (.net .com and some country TLDs) resolved all fine.
for .org i tried debian.org ietf.org gentoo.org and maybe some others with
all failing.

until now i noticed this 2 times on 20191216 and 20200111 and it lasted for
only ~15 minutes maybe less so it is hard to troubleshoot.

so you say the message 'connection timed out; no servers could be reached'
from dig does not mean that my pc got trouble to connect the router but the
router got trouble to connect to root DNS servers? if yes then it is really
strange as there is no issue with other TLDs but for .org i do not get any
answer at all.

looks like something is killing my (or returning) packets filtered by the
presence of .org string.
MITM??? or who is now trying to screw .org??

E

ps: i am using DNSSEC but AFAIK this does not mean the resolve requests are
encrypted...
