Cannot browse one particular site

Hi,

At my workplace we are not able to browse one one particular site.
Following is the error:
Explanation: The request timed out before the page could be retrieved.

Try the following:

    * Refresh page: Search for the page again by clicking the Refresh button. The timeout may have occurred due to Internet congestion.
    * Check spelling: Check that you typed the Web page address correctly. The address may have been mistyped.
    * Contact website: You may want to contact the website administrator to make sure the Web page still exists. You can do this by using the e-mail address or phone number listed on the website home page.

If you are still not able to view the requested page, try contacting your administrator or Helpdesk.

      Technical Information (for support personnel)

    * Error Code 10060: Connection timeout
    * Background: The gateway could not receive a timely response from the website you are trying to access. This might indicate that the network is congested, or that the website is experiencing technical difficulties.
    * Date: 02/09/2010 17:30:14 [GMT]
    * Server: isaserver
    * Source: Firewall

I have tried looking for similar issues in the knowledge base but none have a definite answer or a method to fix this issue.

Could you please help?

Ok guys, I think i have found the solution to this problem. What i did is i called up my Internet service provider and reported this issue. Then we did a few tests:

a. Checked all firewall rules to see if any rule is blocking this site
b. Checked the internal & external DNS entries on ISA
c. Clear all History, Temporary Internet Files, and shut down then restart the desktops
d. While your computer is rebooting, unplug any cable or DSL modem from the power from the wall, then wait 1 minute, plug
     DSL/cable modem back in, and wait 1 minute, then turn on computer again.

Went back to check the site and it started working.

What i could understand from this whole issue is, while very rare, sometimes after a server move or upgrade, either to us from another provider or between our servers, you cannot access your site. Often times this situation is very temporary. This is caused by old DNS settings that your cable modem, DSL router, or other software or hardware device is caching too long.

Can you get to this from outside your network?

When you ping the website name from inside what address resolves?

When you ping from the outside does the same address resolve?

tracert [sitename]    (like tracert www.somesite.com)
Post the results here if you can please.
