There was an issue after moving the forum to out new server. It worked for 99% of the members but there were a handful, mainly with Verizon (but a few others) that just couldn't get in via the URL. They could get in with the IP, but not the URL, which indicated the the domain name servers weren't all reset.
This morning the site was moved to a different IP address for a short time and the DNS update requests were sent out. Then it was sent back to the original (yesterday's) IP address and the DNS repropogated once again. This forced all of the DNS servers out there to reset the IP address. Apparently it worked because now it appears that the Verizon customers can access the site via the URL just like everyone else.
Should be (knock on wood) no more problems.
