The primary NOTAM system is experiencing a temporary outage, but there is currently
no impact to the National Airspace System because a backup system is in place.

NOTAMs provide updates about anything that may effect the safety of a flight.

All active NOTAMs were available until the time of the outage. The agency activated its contingency system to supplement and support preflight briefings and continue flight operations.

The @FAANews is working to fully restore the system, and there may be some residual delays tomorrow morning. Please check with your airline for updates.

We are investigating the root cause and we will provide updates.
 
FAA has set up a hotline to communicate with aviation stakeholders and will send notices every 30 minutes with updates on the system's status.
