(If you've already seen a bunch of these, I apologize for the annoying repetition.)

I suspect Australian FinTech would be more interested in colocating near exchanges instead of trying to beam their orders through space, but I don't work in the sector so I can't say for sure.
Does this have a name? Something like "a race to ridiculousness?" It's so bizarre that it matters that someone places an order a few ms before someone else. And it's probably ns now. No time to stop and think,... just be faster than someone else.

I mean, you can get several houses together. If you split between 5 houses, you still get decent bandwidth (you wont be watching 4k, but then again if you can afford 4k screens ...), and the price is 100 USD + 20 per month. If you don't have any other option this might be decent alternative
Yeah, lots of small villages in Africa or other poor countries will have shared Starlink connections.
This is something to keep in mind and not obvious to people living in 1st world countries.

I's 50%, i would not call that "not a thing in many countries" For mobile, it does not usually matter, you have a smartphone, where you would not host something.

Why couldn’t intersatellite laser links have similar capacity to fiber? In principle, if not practice? Is it because ISLs will require more powerful lasers because the light is focused through a lens instead of guided through a fiber?
>> Why couldn’t intersatellite laser links have similar capacity to fiber? In principle, if not practice? Because laser energies, signal paths, traveling through free space must literally share that space with each other. It is effectively one wire. An underground cable can have hundreds, thousands, even millions of wires lying beside each other without interference. It is comparable to the difference between a wifi…
Could you just add more beams on each satellite?

That remains to be seen. As it stands, these regions don't have the ability to pay for the service (no matter the price - they simply don't have access to bank accounts and credit cards). This is something to keep in mind and not obvious to people living in 1st world countries.

Sydney to Singapore is 6300km as the crow flies. At light speed completely directly best possible round trip time would be 42ms. Light moves more slowly in glass(fibre) and the submarine cables are definitely nowhere direct route, add also routing/switching overhead and the you end up in the hundreds.
Just looked it up. 94ms. Starlink has far more latency. By your lightsped math, Starlink won’t ever be able to compete on latency except in the most rural of areas with poor connectivity since low earth orbit has far more travel distance than convoluted surface routing.
Since I moved on from that last gig, I note that Telstra completed their Sydney-Perth re-cabling project, and the Vocus Perth-Singapore undersea link came online (2018-04).
(I believe east coast traffic routes through Perth to get to Singapore, which was/is/will continue to be part of the problem.)
"lightspeed math" means LEO may well offer performance improvements over terrestrial cabling in many non-obvious scenarios.

Going through the trouble of implementing CGNAT and skipping IPv6 seems like a partially degraded service for the end user though. It's becoming common practice for ISPs to slap all the users between two layers of NAT and calling it a day. You can't run essentially anything on your network (not even an SSH server) without having to have a server on standby and reverse tunnels. I know there are not enough IPv4s but at…
Honestly, it's not that complicated to set up a L2TP or VPN tunnel to a server with routable inbound IP traffic. Most people who would know how to set up port forwarding could probably set it up. I think even some routers support it built in now.
I have been using a starlink beta terminal for 3 months now, ask me whatever you want. Day job is senior network engineer for a regional-sized (4 US states) fiber based ISP. My most important message to everyone reading this is that it's not intended to compete with properly implemented wireline based services. It's going to absolutely blow away consumer-grade highly oversubscribed, bottom of the barrel ku and ka ban…
What's the actual upload speed in good conditions?
