Our servers are up and running well. But we did have a big change over the weekend, in the middle of the night on Saturday we moved to a new hosting environment. For most, this should have resulted in a couple of hours of downtime. I suspect your ISP or your Computer is still trying to access our old location. This can be tested:
On your computer, click the Windows (Start) button and type "Command", hit enter. In the command prompt type "ping www.iflygps.com". It should say "Pinging www.iflygps.com [173.236.5.27]..." If you get a different number, then your DNS is old. You can force your computer to reset it's internal DNS by typing "ipconfig /flushdns" in the command prompt. Also try a reboot.
Please let us know if these suggestions help or not.
Thanks!
Walter
