I found the bash script on this page rather illuminating, adding in my usual sites. (including flyertalk, etc).

When an address is not cached by the local ISPs nameserver, it's painfully slow. for me opendns gives consistent times, even though ping times to the mainland are much slower ( > 2x for opendns.com) than to the local ISPs nameserver.
Interesting. I will try using opendns for a while and see how it goes. I always assumed it wouldn't work very well for me with ping times in the 88ms range, but it seems to be much better than using the ISPs (Hawaiiantel) nameserver.
And I guess that article and script might be interesting for those outside of N. America as well.
