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
TCB
