even
dig @85.68.0.7 google.com
gives me a timeout.
maybe they restrict access ?

a good ISP updates its DNS at least once a day, better twice.
try:
dig @e.root-servers.net distrowatch.com
dig @e.gtld-servers.net distrowatch.com
dig @ns1.mydyndns.org distrowatch.com
starting at the top, each server should point you at the
next authoritative in the DNS hierarchy:
gtld severs are responsible for the com domain,
dyndns for distrowatch.

you know the dinosaur of DNS is Bind,
and while they are open source, their earlier versions
were quite insecure, and they behaved like high priests.

interesting question.
i was thinking it is political, to limit file sharing.
does someone here know how much uploading costs providers ?
