> It appears that the SYN packet triggered three forged RST+ACK packets, each with a relative sequence number 0, as well as incremental TCP window sizes of 1980, 1981, and 1982.
Ah, there's a joke there, if only they used 10 packets :D

Interesting, that would suggest it wasn't an intentional kill-switch (as rumoured initially, testing the capability), but rather likely a misbehaving device / service.
There's also a comment about Pakistan having issues in the same window (tho larger outage for them) so it might be an update / config for some of the same equipment family?
