Pretty sure it's an incident.

If war breaks out, it'll likely be enabled.
Starlink are very low orbit. Easy to bring down.
Very expensive to take down 10-100k at once. No one today has that many antisat-capable missiles stockpiled.
Relevant, Chinese domestic media reporting on China's own perspective:
https://www.scmp.com/news/china/science/article/3178939/chin... ("China military must be able to destroy Elon Musk’s Starlink satellites if they threaten national security: scientists" (2022))
> "Researchers call for development of anti-satellite capabilities including ability to track, monitor and disable each craft / The Starlink platform with its thousands of satellites is believed to be indestructible"
"Easy to bring down" vs. "believed to be indestructible"—some tension there!

#43How would one get around this if they found themselves in such a situation?
In this exact scenario, just use ports other than :443
But GFW certainly had the capability to block all ports. So no one really knew.

outage would mean a connection timeout
in this case, the connection works fine, some extra RST+ACK packets were delivered to your network on purpose

#45Terrible, this is Internet curfew. It's not uncommon to imagine they'd shutdown Internet across border during any war (like against Taiwan).
The infrastructure for that kind of control clearly already exists. What's unclear is how coordinated or deliberate these events are versus being side effects of testing or internal changes

You probably mean the USA? After all, it was China and not Asia which was responsible for the incident ;)

#47Think of how many people who have remote jobs with American companies couldn't connect to their meetings while they "work from home" while secretly being in China! Normally they have to fight VPN issues anyway, but having a sovereign state inject your packets is certainly a fun new one.
How many people suddenly "lost internet" mid-meeting and had to blame it on their router...

No it won't but if it did would take just few hours for china to shoot a bunch of them down and with how tightly packed their orbits are the debree would take care of the rest.
potentially very dangerous for everyone if they did that. could make it impossible for even them to make a launch. Kessler Syndrome is nothing to toy with.

But "good reason" depends a lot on your perspective

Could you bring something like a starlink mini for backup i wonder? Id imagine this would be very worrying being stuck there as a foreigner in such a situation.
Starlink connects you to the internet via a ground station in the country where you are registered, and the antenna will also only operate in an approved zone (depending on your country and account type). You cannot use it in China.
