If I understood it correctly Starlink doesn't send between satellites yet, only sat ground. Sat sat is a big point of starlink and when they roll that out the latency should go down, especially for starlink starlink comms I imagine.

Yes that’s a few more years before then, and the more sats the more capacity and the lower the latency.

What is the lifetime of a SpaceX satellite?

Judging from their high launch cadence, it seems satellite-satellite communication was just a means to excite the fanboys and motivate their employees, the same way the peddle the Mars stuff.

Have they said anything about pricing yet? This would seem like a decent solution for roaming data during travel too.

Nothing specific, I think they are still figuring that out, but Gwynne Shotwell, the president of Spacex, is hinting a bit I think with:

> Shotwell said millions of people in the U.S. pay $80 per month to get “crappy service.” She didn’t say whether Starlink will cost more or less than $80 per month but suggested that would be a segment of the public the company would target as well as rural areas that currently have no connectivity.

And if you can break the speed of light, you don't need a second exchange.

It’s quite easy to “break” the speed of light in fiberoptic glass.

But it's not that useful even if you pour a glass cube over the whole exchange to slow it down.

Why would HFT even consider using it? They are located as close as possible to the exchange they operate on, not across states or halfway across the world.

Arbitrage between multiple exchanges requires data to go from exchange A to exchange B as fast as possible. Light in vacuum is faster than light in fiber.

Light in vacuum is only faster if it goes in a straight line from point A to B, not if it zig-zags across 50 satellites.

Fantastic. I'm keenly curious on how this will work with national regulations. Having a single global ISP is very attractive on the surface and that's with the huge caveat on monopoly, but as an additional option. I'm just not sure how this will interact with some nations' policy/restrictions. Looking at this aspect very much.

It's going to be very interesting for me. I plan to live on a sailing yacht and travel the world permanently, StarLink will make my working options a lot more flexible. Presently people are forced to see out their contracts over potentially dodgy marina WiFi.

The regulatory situation might get quite complicated I think, for example if you're in international waters, connected to the internet by a global ISP whose infrastructure is also outside of territorial limits then whose regulations do you have to comply with (besides your clients)? What's stopping the likes of Google poaching the concept of Radio Caroline, planting a datacentre somewhere in the North Sea and raising a two-fingered salute to any sort of data protection laws?

This is only a few Mbps slower than my Fibre-to-the-Cabinet broadband in the UK provides. And I'm living in a town; plenty of rural areas are much slower.

It's actually marginally faster than mine - UK town in the north also.

Latency to where? One of the promises of starlink is reducing latency over mid distance - say transatlantic or even across the states, due to using vacuum rather than fibres. Will be interesting how HFT use it. Starlink network is nowhere near complete so I’d expect things to only get better (until customers start piling on)

If I understood it correctly Starlink doesn't send between satellites yet, only sat ground. Sat sat is a big point of starlink and when they roll that out the latency should go down, especially for starlink starlink comms I imagine.

I don't understand how this is meant to lower the latency. Currently:

    ground  satellite  ground
With satellite links:

    ground  satellite  satellite  ground
How can the latter possibly be faster?

Edit: Thanks for all the responses. I'd been assuming it was a test of Starlink latency only, but if it's Starlink -> ground station -> open internet -> ISP then it would make sense how that would be slower than a pure Starlink connection.
