Some time ago I published a Web user control that employed NOAA Web Service and displayed weather forecast. Since then I received a few emails from those folks who downloaded the control with complaints that it stopped working. The reason was always the same: timeout when calling NOAA server. Increasing timeout period didn't help. Apparently we are not alone and the problem does not seem to be control-specific. NOAA sample pages still work, but they use postback from a browser, not RPC calls to a Web service from code.
I also made a small C# Windows Application in VS 2003 that called NOAA Web Service. It ended up with timeout as well. So the issue does not seem to be related to ASP.NET or Framework 2.0.
I recenlty sent an email to NOAA Web master asking for help. I'll keep you posted.
