FAA Data Outage
Notices & outages ...FAA DATA OUTAGE...
NWS is reporting a problem affecting FAA, NCO, METAR and PIREP. Some data may be missing, delayed or slow until it is fixed.
The message says NWS is actively working the issue, so this is a live situation rather than a closed one.
FAA is the Federal Aviation Administration, which exchanges aviation weather data with NWS, NCO is NWS Central Operations, which runs the computing behind the forecast models, METAR is routine hourly airport surface weather reports and PIREP is pilot reports of conditions aloft.
For most people this is invisible — forecasts keep coming. It matters most to anyone pulling NWS data directly, and to forecasters who lean on the affected feed.
