The response time depends on network peering from their anycast locations. I am seeing different response times based on test locations.

From US:

  # ./dnseval.py -f google-vs-quad9.txt -c 50 -C yahoo.com
  server      avg(ms)     min(ms)     max(ms)     stddev(ms)  lost(%)  ttl        flags

Perhaps they accidentally lifted the blocking rules. Or it will drop as soon as they upgrade their censorship software.

I wish their client had first class support for other operating systems like FreeBSD. Current client is too debian/ubuntu specific.

This is very interesting that "accidentally" all the parts have distinctive marks that can be linked to a B777 aircraft.

wasn't this obvious from the beginning? And the same would happen to RockMelt as well.
