When I do a name lookup for yahoo.com on dns1&dns2.webbuilders.com it does seem very slow. ranging from 300-800ms. By comparison, the same query to our slowest nameserver, which is only on a 256k line, took 102ms the first time, and then 50-60 ms after that. Yours never seemed to be cached. -- Aaron Lynch System Administrator NineWire Digital Solutions
