tunnelbroker nameservers down?
« on: December 07, 2010, 06:52:35 AM »

Yesterday and today, I have noticed that the two nameservers on the tunnelbroker info page are having issues.  Is anyone else seeing this?
Anycasted IPv6 Caching Nameserver:   2001:470:20::2
Anycasted IPv4 Caching Nameserver:   74.82.42.42

I am seeing things like this:
$ dig www.tunnelbroker.net. @74.82.42.42

; <<>> DiG 9.7.1-P2 <<>> www.tunnelbroker.net. @74.82.42.42
;; global options: +cmd
;; connection timed out; no servers could be reached

I finally had to change the upstream nameserver for my network back to my ISP, but they are not part of the Google over IPv6 program, so I am no longer l33t.

I am still seeing sporadic behavior -- some timeouts, some long delays, and some successful queries to the tunnelbroker anycasted dns.  I haven't made any changes on my end, so it must be the network in between if it is working for others.

I noticed some oddness the other day too.  It wasn't returning AAAA records for google through my name server which has a forward only zone set up for google.com pointing to the HE anycasted server.   But it seemed to start working after I kicked my BIND, so I figured it was on my end.

It helps to state which tunnel-server you are using since the resolver IPs are anycasted at all locations.
If this was the Fremont-2 facility tunnel-server, it required a hardware swap which has since been completed.
