Odd DNS issue

[dsd17]

Sunday evening our domain name renewed (yearly renewal). Now, anywhere inside our office, the website pings to a GoDaddy IP address and if you go to the url, it redirects to another website hosted on our server. Everywhere else in the world (or the 7 places I've checked at least) show the correct IP and website when browsing or pinging. We have the domain registered at GoDaddy, but the NS are at dnspark. Our website is hosted offsite from our office at a CoLo.

Two weird things are happening inside our office:

1. The website is being redirected to another website on our server.
2. When I ping the website from our office, an IP from GoDaddy shows up.

How can I reset the DNS here? Would a simple reboot of our gateway do the trick (we have ATT Uverse)?

The website in question is readysetbackup.com.

C:\>ipconfig /flushdns on each computer.

Unfortunately that didn't do anything. Plus, most of the machines we work on are macs. I'm just gonna reboot the gateway and see if that fixes it.

Edit: restarting the gateway didn't do anything either...

Edit 2: restarting DID solve the problem. Just took a while to propagate down to the machines.
