ATT Uverse DNS Propagation taking forever...

We updated the nameservers to one of our company websites on Friday.  Very shortly after, the changes had been reflected on all of our mobile phones but not our office network (ATT Uverse).  I figured it might take a couple hours, so thought nothing of it.  The website worked fine for us on our home networks as well.

 

It's now Monday and we're back in the office, but still none of us can connect to the website and we are all getting connection timeout errors.

 

I have checked numerous DNS sites to verify the changes have been propagated and they are.  I have cleared by browser cache/cookies and flushed my computer's DNS cache.  By all accounts, the website is live and working, but on this ATT network it is not reachable.

 

How long is the delay for DNS propagation on ATT and why is it taking so much longer than everywhere else?  I need to work on this site today...

We'd love to help, @jmanly3.

Our DNS propagation can take up to 72 hours to fully update.

After changing the nameserver, have you checked to see if you can ping the new URL from a device in the office? You can do this through the Gateway, or on a Windows Vista/Windows 7 or 8 computer by following these steps:

  1. Click Start
  2. Go to All Programs
  3. Open the Accessories folder and double-click Command Prompt
  4. Type "ping [URL of the website]", then "ping [IP address of the site]" to see if either are pingable.

For Mac 10.1-10.7 or Mac OSX follow these steps:

  1. On the menu bar, click Go and then Utilities (if there is no Utilities option, click Applications, then Utilities).
  2. Select Network Utilities
  3. Select Ping
  4. Ping both the URL and IP address

If the URL cannot be pinged, the TCP or IP setting is possibly corrupted and must be reset.

Let us know what type of operating system you're running, and we can assist you further.

Your post only shows how to ping an IP address. We need a solution to speed-up DNS updates. AT&T taking up to 72 hours is beyond reasonable expectations, especially for business customers. So what is the solution? What do we do other than switch ISP?
