My interpretation: Definitely a WL issue. My data forwarding has been interrupted 3 times since yesterday, and each time I've had to log in to WeatherLink and put a check back in the box to upload to Weather Underground. And yes I have saved my settings after each go-round. Have had no error messages, email alerts, etc. It just seemed to stop. In all cases WL has continued on happily, both on my IPhone app and on the web. There are lots of people less than satisfied with WU for a variety of reasons but I think they are innocent in this instance!
