Hi Bob,
Thanks for the clarification. Since the problem started when we moved our servers to our new colocation last week, it is now sounding more like it may be a DNS issue. The next thing I recommend trying is flushing your DNS resolver cache which can be done via the following process if you are using Windows:
1) Select "Run" from the Windows "Start" menu.
2) Enter "cmd" in the ensuing field and click "OK".
3) Then, in the black DOS window, type "IPCONFIG /flushdns" and press the "Enter" key.
This procedure does not always work the first time so, if you continue to experience the same problem after trying that measure, it may be worthwhile to try it a few more times. If you are using MAC OS, you should be able to find instruction on how to flush your DNS by looking up "Flush DNS" on Google.
If you are still unable to add snipes to your account after trying this measure, please let me know via this thread, and I'll see if I can come up with some other suggestions that may resolve this issue.
