I'm having a rather annoying problem. It seems when I try to navigate

so before it hangs again.

Turns out that disabling IPv6 solved my problem....Maybe my router
doesn't like it? But at any rate, doing that seemed to improve my
connection all around so I'm happy :)

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..
