Slow hurricane electric tunnelling DNS servers
« on: August 06, 2011, 11:39:48 AM »

The DNS servers I am supposed to use
Anycasted IPv6 Caching Nameserver:2001:470:20::2

Anycasted IPv4 Caching Nameserver:74.82.42.42

These appear to respond very slowly, typically >0.5 s (see testing details below), although the server responds in 15 ms to pings. I would like to use them, as they are whitelisted by google , etc...




------------


For instance, if I past "echo sob","nslookup www.cnn.com" "ping www.xs4all.nl" in my command prompt window, I see
(Look at the timestamps of the prompt, "prompt $t)" )
20:52:00.75)echo sob
sob

20:52:42.06)nslookup www.omroep.nl
Server:  ordns.he.net
Address:  2001:470:20::2

Non-authoritative answer:
Name:    omroep.nl
Address:  145.58.30.3
Aliases:  www.omroep.nl


20:52:44.73)ping www.xs4all.nl

Recursor probably needs a kick or something. What tserv do you go through to reach it so I know which of the 25+ anycasted recursors to go look at?

EDIT - nvm, saw your account's tunnels are through AMS, will work on it.
EDIT - Node had a memory issue, pushing out a nice clean config and making sure all is well with it. Tunnels are already rebuilding, and recursor service is responsive once more.
