Earthlink's broken DNS affecting Tor nodes?

[Matt Ghali]

yes, it is a bad thing. the easiest thing to do (if you are running 
tor on a unix box) is to install BIND 9 as a caching nameserver, and 
configure your resolver library to use BIND instead of your ISP's 
nameservers (man resolv.conf).

Most modern unix distributions come with BIND 9, and just require 
you to enable them somewhere like /etc/rc or /etc/sysconfig.

Anyone running tor should consider doing this, as you'll be making 
name resolution almost an order of magnitude faster; in addition to 
not having to trust nameservers configured to lie by a marketing 
department.

If you're running Windows; well, good luck.
