Any source for the claim of a ground stop? I see plenty of flights still taking off.

MESSAGE:

EVENT TIME: 11/1126 - 11/1500 UAL GROUND STOP ALL FLIGHTS / ALL DESTINATIONS PER USER REQUEST DESTINATION AIRPORT; ALL FACILITIES INCLUDED: ALL GROUND STOP PERIOD: UNTIL 1500Z REASON: USER REQUEST REMARKS: US NOTAMS SYSTEM DOWN

UAL = United Airlines, not “all North American flights” as OP claimed

The advisory posted by OP wasn't UA specific. You're looking at a later one.

The most recent one seems to say something like that. ATCSCC ADVZY 023 DCC 01/11/2023 ALL UAL MAIN AND SUBS GROUND STOP

Not that I know how to read it. The event time is three minutes ago.

Reads United Airlines apparently.

My understanding is that applies to United Airlines and it’s regional partners. It seems each airline is making their own decision.

This Reddit post seems to have more info: https://old.reddit.com/r/flying/comments/108yjgz/faa_notams_...

Air Traffic Control System Command Center Advisory 23 by the Traffic Management Command Center (DCC) at date [..] - all united airlines ... ground stop.

Here is about ground stops: https://www.faa.gov/air_traffic/publications/atpubs/foa_html...

Advisory 028 is a nationwide ground stop: https://www.fly.faa.gov/adv/adv_otherdis.jsp?advn=28&adv_dat...

This was based on a P.A. announcement from a gate agent, so not authoritative. I've updated the title to reflect what is in the link.

I can see that East Coast UA flights are currently delayed because of this.
