Actually, if you suspected your ISP's DNS to be invalid, you could use
someone else's. For example go to Network Solutions website and do a who-is
lookup on a known site, and then copy their two name servers to your own
setup and see if that would fix the problem.
You could even do a who-is lookup on cisco.com and see that they are using
ns1.cisco.com and ns2.cisco.com. Then do a nslookup, followed by a server
ns1.cisco.com, followed by a cisco.com that would give you
Name : cisco.com
Address : 198.133.219.25
Then exit nslookup and try to ping 198.133.219.25.
If that goes through okay, and your ping www.cisco.com doesn't - you know
you have a DNS problem somewhere.

One reason why someone might post such a question to a newsgroup is to help
troubleshoot DNS problems. If other users (like the majority of us, it
seems) can get to the website and he (the original poster) could not, that
might point to a problem with his ISP's DNS server being out of sync.
Or it could be a problem with reachability at the IP layer, but again, he
would have no way of knowing if it was just him who was having the problem,
or everybody. If the Cisco web server is down, then everyone would be
having the same problem and there's little he can do. If it's just him,
then he would know that it's time to get on the phone with his ISP.
Either way, such posts are valid, imo.

Why do you think it is down? What do your pings and traceroutes show?
How would the information that I can or cannot reach it be helpful to
you? If you've done enough troubleshooting to think the problem is
at your end -- and I would hope anyone on this list would do so --
aren't you just going to keep retrying?
