Yes, in the past week (6-17-09) the NOA has LOTS of downtime.
I am not sure why, we tried contacting them with no luck. The service seems to be up and down.
The GOOD NEWS:
Our release 1.5 will Cache all RSS XML (Weather, news).
So, if a service goes down, you will get the last good know result. So, you will not feel (see) small interruptions in RSS feeds.
If you want a private build to test for 1.5, please email me and I will get you a test release.
