I was booked on a 2/4/26 flight but received this strange email. Looking at the reservation now, my original outbound is entirely gone and only my return remains.

I called the number in the email but the agent had no context and asked why I was trying to change my return - she couldn’t see the original flight and was annoyed that I was insisting this itinerary used to have more segments.

Calling the 1k desk and a nice rep shared “I saw something this morning [11/22/25] come out to all of us agents. It said….you know that Microsoft thing that happened last year that grounded all the flights…they’re doing that again so all flights before 9am on Feb 4 are cancelled“ - I don’t think a Cloudflare outage is schedule like that, but that’s all the context I got.

My cancelled flight is a daily international flight that operates year round departing a hub. It is scheduled and bookable every day in the calendar except 2/4/26. It also departs well after 9am. Flights to this destination departing from other hubs and landing at similar times are still operating and bookable.

My connection that departs and lands well before 9am however is also deleted from my itinerary, but also still operating and bookable.

This is not a one off flight but something about the specific day. I saw someone post on reddit yesterday about a 2/4/26 cancellation for a different route touching a different hub.

I can handle the rebooking but can anyone provide context on what the cause of this is?

Ultimately just curious because it’s very weird.
