That drops the IPv6 lookups - you may be able to just disable IPv6 in
your browser, but glad it helped a bit.
Facebook is still going to load slowly due to 30 second TTL on the A
record for www. and 10 minute TTL on inconsistent NS records. They are
announcing a set of NS records from the .com TLD servers, then handing
out completely different short-TTL NS records where the client needs to
perform final lookups, then handing out a final record that expires in
30 seconds, so the client has to go do it all again.. the price of
popularity and having to implement gss load balancing, I suppose..
