two thing comes in mind.
1. Do a telnet to the ip address of www.yahoo.com on port 80 and see if
that works.
2. Do an nslookup on the proxy (with DNS entry pointing to the ISP) entry
and see fi that works.
If ping and traceroute is working, most probably problem would be
application related.

Subject: ping and trace-route successful but www failing
Dear all, we're a ISP and one of my customers is experiencing a strange
problem accessing www.yahoo.com. They're able to ping and trace-route (IP
address & DNS) to the site but not WWW. When the URL is entered, the
browser
attempts to load the page but fails and returns an error: page cannot be
displayed or not available.
Other customers connected to us are not experiencing this problem, we even
tried bypassing customer firewall by connecting our laptop directly to the
internet router Ethernet port, but the problem persisted. This might not
be
an internet routing problem as other customers are not experiencing
similar
problem, only this one particular customer. We even tried swapping a new
C1721 running 12.2(11)T but that didn't help either. The problem only
started last week, before that they were able to access the website.
Just wonder if any one of you has came across a similar problem... any
help
or advice is much appreciated.
Cheers,
Mohan
