A Fediverse community for open-ended, thought provoking questions

Rules: (interactive)

1) Be nice and; have fun

Doxxing, trolling, sealioning, racism, toxicity and dog-whistling are not welcomed in AskLemmy. Remember what your mother said: if you can't say something nice, don't say anything at all. In addition, the site-wide Lemmy.world terms of service also apply here. Please familiarize yourself with them

2) All posts must end with a '?'

This is sort of like Jeopardy. Please phrase all post titles in the form of a proper question ending with ?

3) No spam

Please do not flood the community with nonsense. Actual suspected spammers will be banned on site. No astroturfing.

4) NSFW is okay, within reason

Just remember to tag posts with either a content warning or a [NSFW] tag. Overtly sexual posts are not allowed, please direct them to either !asklemmyafterdark@lemmy.world or !asklemmynsfw@lemmynsfw.com. NSFW comments should be restricted to posts tagged [NSFW].

5) This is not a support community.

It is not a place for 'how do I?', type questions. If you have any questions regarding the site itself or would like to report a community, please direct them to Lemmy.world Support or email info@lemmy.world. For other questions check our partnered communities list, or use the search function.

6) No US Politics.

Please don't post about current US Politics. If you need to do this, try !politicaldiscussion@lemmy.world or !uspolitics@lemmy.world

7) No Hit-and-Run questions.

Please don't delete your post for no apparent reason. If you plan on deleting a question later, say so in the post, or if you feel that you have a good reason to remove it, message a mod beforehand. It's not fair to the ones who took their time to answer, and it's not in the spirit of the community.

8) No Bots.

Posts or comments from bots, LLM's, AIs, Neural Networks, Transformers, or Marvin the Paranoid Android are not welcome in AskLemmy. Real humans only please.

Reminder: The terms of service apply here too.

As of thirty-ish minutes ago ALL commercial air traffic in the US is grounded until further notice.

Anyone got any idea what’s going on? There are very free details about the situation I can find online right now.

Beyond that, all I've seen so far is:

Markwayne Mullin, the secretary of homeland security, says Trump administration officials blamed a telecommunication outage but said they did not know its cause and that it would “take some time” to fix the issues grounding flights.

per NYT's reporting: https://www.nytimes.com/live/2026/11/13/us/ground-stop-nationwide-flights-faa/d2ae2ce1-ac6b-59ad-ad8d-daef4e181b34

Edit (longer quote further down from Mullin):

Markwayne Mullin, the secretary of homeland security, blamed the ground stop on a telecommunication outage but said Trump administration officials did not know the cause, adding that it would take an extended period of time to fix the issues. “This isn’t going to just be resolved and turned around within the hour,” he said. “This is going to take some time.”
