Interesting snippet from the terms of service: > For Services provided on Mars, or in transit to Mars via Starship or other spacecraft, the parties recognize Mars as a free planet and that no Earth-based government has authority or sovereignty over Martian activities. Accordingly, Disputes will be settled through self-governing principles, established in good faith, at the time of Martian settlement.

I mean, I'm pretty sure that Elon added this to potentially establish his own governance over Mars(or his descendants) but yeah, I think good luck with that.

Are you sure about that? I see there's an article from a couple years ago talking about quad-core A53 CPUs with FPGAs. That's most likely used for the satellite avionics, rather than for the starlink radios. While it's possible the avionics and the radios are tightly coupled, I would be surprised if they were. They're probably mostly separate for fault tolerance reasons. I suspect FPGAs wouldn't be fast enough to do…

FPGAs are extremely commonly used in the RF telecomm space. You don't implement a multiplier in the free-form FPGA fabric, instead such FPGAs have banks of 'DSP blocks' which essentially give you hard silicon ALUs which you can then hook up however you want. This gives you extremely flexible and potentially massive parallelism with very tight latency guarantees, and you don't lose a huge amount of performance because…

FPGA are also way easier to harden to sustains radiations in space. The custom silicon you mention is done by a french foundry, STmicroelectronics.

Other than the cool factor I’m not sure why you’d want it in a city. I get gigabit for 60$ a month and star link will never match the latency I get due to physics. If it was cheap enough I’d love to get it for traveling but it should be used for things like that not to replace your inner city connection.

Backup internet.

I live in a remote, medium-sized city and need an internet link that constantly works. Comcast usually fills that need, but there are occasional outages. T-Mobile, Verizon, and AT&T's fixed internet offerings are not available where I am.

Starlink is what I've been waiting for :)

I've seen the figure of 130W used by the ground station. 100W is a lot, from memory 4G cell towers are only ~10W. What's the kind of RF exposure you get around a ground station? Is SpaceX giving recommendations around where to place the ground station (eg: not on the top of your house)?

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…

I expect a fair bit of interest from latency-sensitive markets (eg finance) here in Australia. A few years ago when I was in the WAN optimisation space, IIRC Sydney/Singapore latency was ~150ms, partly raw distance, partly because the route was physically quite convoluted. There's some expectation that once Starlink's mesh comms ramp up, it'll be significantly faster to go up to a bird, across through one or more at…

Isn’t the current latency between Sydney and Singapore 15ms or less by now? No one who is latency sensitive should be using Starlink unless they are in some incredibly remote location. (And they should move if they are 150ms is a cosmic age in low latency trading)

I regularly get 12ms latency to google over my DOCSIS3 cable coax connection.

I just checked mine. I get about the same. Pinging 8.8.8.8 with 32 bytes of data: Reply from 8.8.8.8: bytes=32 time=12ms TTL=115

8.8.8.8 is 13ms , but how does Cloudfare (1.1.1.1) get to 1ms ?

Reply from 1.1.1.1: bytes=32 timeSome sort of local caching going on.

Is there any mechanism by which we (in general) or a client specifically could use an expensive low latency for say browsing and a high latency but wide/cheap pipeline for bulk transfer? I can imagine being able to do this when you control both sides by letting one type of data flow over one IP and the other over a different one with different peerings. But I wonder whether this is generally available.

If either your ISP exposes that ability or if you maintain multiple outbound connections, then yes. But I don't think this is commonly implemented today, however. You would probably have to configure your own routing table to direct traffic for each application through the appropriate link, but that's completely doable as long as you can write rules to distinguish the packets (for example based on destination).

Yes I can imagine using iptables to work but it was my understanding that this would only be able to determine the next hop and I couldn’t get it to force the decision higher up the chain. This would mean that every party along the chain has to play ball.

I can imagine that it would be beneficial for the internet experience if we could segregate low latency traffic (human/hft) traffic from hulk traffic such as video. Although this goes against net neutrality I suppose.

I live on the Western Isles of Scotland I tried random places near me to see if they show up on Starlink The nearest one to me is Stornoway (the main town on Harris) I am about 50 miles away from it Would this solution work? Currently I am happy with my 4G internet but always interested to try something else. https://www.google.com/maps/place/57%C2%B038'54.0%22N+7%C2%B... Also the Satellite doesn't look like it would…

Try using a Plus Code? The link you sent is 9C9MRJ9C+XP (visible in the left panel of Google Maps when you click on a location) which isn't on land and is rejected by the Starlink website, but "V84R+RR Isle of Scalpay" (the nearest land) gives me the same pricing as I see for my location in Edinburgh. So I suspect you'd be fine.

Thanks, I sent the wrong link (updated)

The plus code for my area returns nothing, however for a satellite that is ~500km above me, surely subscribing to a location that is 27 miles away from me won't make a difference?

> beta-only limitation though There's no way you are crossing borders with it and transmitting from a country where it's not approved.

That's an interesting point. I noticed this: https://www.canadasatellite.ca/Satellite-Phone-Limitations.h... "While satellite phones work essentially anywhere on earth, there are some physical and political limitations." one limitation was not what I expected: "Cuba restricts the use of satellite phones because they’re seen as tools for subversive purposes" Back to starlink - I think distributed living is a wonderful…

As a side point, Cuba’s internet is also filtered and such, but was remarkably easy to get around with an SSH tunnel. Was handy when I was there!

One thing my current ISP still does is returns an ad-laden search page any time you visit a domain that doesn't resolve.

Super annoying. FYI every ISP I’ve had that does this has some setting buried somewhere that lets you turn this off. If not that, you can usually bypass this by setting your router (or computer directly) to use 8.8.8.8 (Google dns) or 1.1.1.1 (cloud flare dns) as a resolver. I’ve only heard of a couple of cases where ISPs sniff all dns and rewrite NXDOMAIN responses, and the answer for those is some kind of unpleasan…

Does DoH help with this?
