NWAC Telemetry?

I just noticed this afternoon, 5/01, that all NWAC telemetry links teminate on 4/30.  I've not seen this in past years, where telemetry stations continue reporting well into summer & sometimes fall, or until they fail.  Is this an temporary anomoly, or has the plug been pulled?  Would hate to lose this essential info.  Does anybody know anything?

It's was most likely a server or computer issue at their office. The individual stations are still working, but the NWAC staff isn't in the office on the weekends to correct the issue immediately. Looks like the problem is corrected though.

Yes, thanks to whomever corrected the outage. In reflecting on NWAC's continued telemetry service long after they shut down seasonal forecasting, I am really grateful for their telemetry and the help it provides in planning for year around mountain activities. My thanks to NWAC and the Friends for providing the resources making it possible! Gerry H
