FWIW, I gave a talk about Starlink - insights from a year in - at last
week's APNIC56 conference in Kyoto:

Also well worth looking at is Geoff Huston's excellent piece on the
foreseeable demise of TCP in favour of QUIC in the same session. One of
Geoff's main arguments is that the Internet is becoming local, i.e.,
most traffic goes between a CDN server and you, and most data is
becoming proprietary to the application owner, meaning it suits the
Googles and Facebooks of this world very well not to be using TCP for
its transport, but rather pull the transport specifics into the
application layer where the have full control.
Food for thought, especially since LEO networks are a particularly bad
place to put local content caches, since the concept of what's "local"
in a LEO network changes constantly, at around 20,000 miles an hour or
so. Spoke to a Rwandan colleague who installs Starlink there and sees
all traffic to anywhere go via the US with RTTs of nearly 2 seconds,
even if the Rwandan user is trying to access a Rwandan service.
About to hop onto a plane (ZK-NZJ) tonight with free WiFi (Ka band GEO)
enroute to Auckland in the hope of getting a better experience than last
time when the system seemed to run out of IP addresses on its DHCP.
