[Starlink] Starlink no longer available to the Ukrainian army?

[Ulrich Speidel]

My 10 cents worth: If you divide the total annual Internet usage 
worldwide (a ballpark figure at best) by the total number of users 
worldwide (another ballpark figure) and then by 365*24*60*60, you get a 
rate of (ballpark) 1 Mb/s. b as in bits not bytes, M as in Mega not m as 
in milli (someone needs to tell Starlink that or are they promising 
people a lot less than we think: 
https://www.starlink.com/legal/documents/DOC-1002-69942-69?regionCode=US?). 
That means each Internet user generates, on average, 1 Mb/s of traffic 
on a 24/7 basis. Of course, we'd expect them to generate at little less 
off-peak and a little more during peak hours. But it's a handy rate to 
compare other numbers to.

So if you then consider the 15 Gb/s that Nathan quoted earlier on, 
that's really only about 15k users, if averaged. If it's a peak figure 
(likely if Elon shouts about it) then that's likely a lot less than 15k 
users. Now just a gentle reminder that Elon's still having trouble 
provisioning to all of Montana, and there's just over a million folk 
there. Ukraine has over 35 million - even if you take all the refugees 
that haven't returned out - and it's not orders of magnitude larger than 
Montana either.

So it's plain obvious that Starlink is not carrying most of the Internet 
traffic from/to Ukraine. Far from it. I don't think Elon has claimed 
this anywhere, either, but the fact that this claim is making it on this 
list just goes to show how effective he is at getting people's attention 
(and leaving such false impressions uncorrected). That said, it's 
probably carrying a fair amount of Ukraine's frontline unit traffic now. 
In fact, Starlink's probably exclusively mil/gov use in Ukraine right now.

Fibre seems to be what is propping up the rest - and quite effectively 
so. But not as glamorous. Who'd want to know about low power fibre laser 
diodes when you can have space lasers next year?
