Hi all

We have two ISP access at the company I work at. My customers use one and I use another. My customer cannot access yahoo.ca or yahoo.com this morning even though I can access them from my other supplier. So I know the sites are not down.

When I do a trace route from the faulty IPS, I get all the way to the site, so its not a routing issue. When I try a telnet on port 80, for yahoo.com, I was able to do a get (but still not able to do it through the browser) but from yahoo.ca, I could not. When I changed the IP NAT address that my customers use to browse, all trouble stopped. My IP does not seem to be on any blacklist that i can see (from my research this morning). So i cannot explain what is going on.

Can anyone offer leads for investigation?

Thank you

a network admin resetting a permissions list in a router?

Or maybe they have a routing table entry that's set wrong to forward traffic to an malformed address or something?

Can't be for sure. I've been into Yahoo Mail all morning.

We thougth about that, but I figure that if it was a routing issue, we would not be able to do a full traceroute or connect with a telnet on port 80.

I've been trying to figure out how to contact Yahoo but their site keeps giving me the run-a-round. If any one know how to contact Yahoo support, I would really appreciate the information.

If they are restricting/choosing routing based on protocol, then the ping/traceroute might get through where an HTTP/Port 80 request might be getting misdirected.

Just a thought.

and found no errors, but it wouldnt let me log in. 1 time was an Avast update, the second time I found that yahoo cookies were set as blocked.
unblocked the cookies and have had no issues since

Edit: No idea how all Yahoo cookies became blocked either????????

As we were about to check your suggestion, we found that the problem had went away without explination.

Thanks anyway for the help.
