Can't access our own webserver from our office only.

Asked by rennocb in Web Hosting, Hypertext Transfer Protocol (HTTP), Internet Service Providers (ISP)

Tags: website, http, ftp, ISP

About 10 days ago, we suddenly stopped being able to access our company website. Our website is hosted by Hostway. We could not reach it via HTTP or FTP from our office building. I called Hostway to have them check it out. But because it seems to be accessible from all other location except our office, they claim it's not their issue. I also contacted our ISP and again, because it seems that we have no trouble accessing any other website, they claim it's not their issue. So I guess that would suggest that it's our issue... however, no changes have been made to our domain controller or firewall/router.

We found that if we used an annonymous proxy (annonymouse.com or megaproxy.com) we could reach our website.

We have 2 internet sources. Cable internet for our data traffic, and a T1 line for our VOIP traffic. We found a workaround by having rerouted all our HTTP and FTP traffic for that specific domain and IP address to our T1 line. So obviously, this issue is related to our cable internet connection somehow.

I don't understand what could have spontaneously changed. The only thing questionable is that I gave someone our website login credentials the week before this happened so that they could add a page to the website that our marketing dept. needed. Is it possible they could have changed something at the webserver?

A Traceroute shows that we are reaching Hostway, but then time out...

Anyone have any ideas?
