Old topic, new idea. Stolen from
http://www.linuxdoc.org/HOWTO/DSL-HOWTO/tuning.html
5.4.1
Some Web pages won't load. For PPPoX users, the MTU value could be too high.
This will cause packet fragmentation, and likely will cause misbehaving
routers to fail to route your requests per Path MTU Discovery specs.The
correct ppp0 device setting should be a maximum of 1492, but actually it
needs to be 8 bytes less than any router you pass through on the way to the
site. If a router somewhere is misconfigured, you could have problems. Try
experimenting with lower MTU values. Any LAN hosts behind the connection,
may even need to be even lower -- 1452 or maybe even 1412. If ECN is
enabled, it might also cause this problem. Cured with "echo 0 > cat
/proc/sys/net/ipv4/tcp_ecn".
Could a router somewhere be "blocking" your http requests?

My ACS DSL has noissues with any of the URL's mention in this thread.

This confirms the path is being dropped. You can grab this and more info
on this issue by using http://nitrous.digex.net/mae/maew-lg.html
and the Looking Glass script they have.
It also offers a bit more intuitiveness to use the -A when using
traceroute and thus spilling the AS # of the hop.
