 ## What Happened ##
-At 04:09 UTC on Friday the 19th of July, [Crowdstrike](https://www.crowdstrike.com), a cyber security software producer, released a problematic signature update to it's endpoint protection client. This caused Microsoft Windows systems running the Crowdstrike agent to randomly blue-screen (BSOD) and take down the system. Crowdstrike has the majority market-share among a wide variety of  large enterprises including airports, airlines, hospitals, supermarkets and media companies.

-As delays were created in various parts of the world, the US Federal Aviation Authority (FAA) issued [Ground Stop Advisories](https://www.fly.faa.gov/adv/adv_list.jsp?WhichAdvisories=ATCSCC&AdvisoryCategory=All&dates=Friday%2C+07-19-2024&Gstop=Gstop) for AAL, UAL, DAL, AAY and NKS airlines starting from approximately 05:45 UTC. The cited reason calls out "communications system issues" which were critical enough to warrant the drastic action. This meant that aircraft already in the air could continue their journey however, this did halt take-offs, stranding passengers and causing massive delays across the country.

 At [plane.watch](https://app.plane.watch), we've queried our database history and put together a graph that highlights exactly how this impacted the number of planes airborne over the US during the day. Plane.watch has more than 300 ADSB feeders based in the US that feed us data about planes within their coverage including position, altitude, heading, type and operator.
