AT&T DNS issues on new DS3
Posted on 2007-11-14
We recently moved from bonded T1's with MCI/Verizon to a DS3 with AT&T. Now every test we do in terms of file transfers, downloads, and uploads show great speeds. However, when we go to a web site, it seems to take much longer to load. I have AT&T DNS servers as my forwarders on the internal DNS server, in the firewall, and the router. They seem to only have 4 DNS IP addresses, where MCI had a large number of them. I have been doing searches and found some information about previousl AT&T DNS issues, but nothing recent. Is there anyone who has experience with their server and can provide some feedback. We were really hoping this would greatly improve the users experience, but even those of us in the IT department notice it. New routers and firewalls were purchased for the DS3, and the configurations have been double checked by support those manufacturers.
