I imagine it is illegal for Starlink to not geofence service to prevent Russians using it for exactly that purpose. Sanctions still exist, after all.
Yes, in Kursk, maybe. However this is in Ukraine.

Yes, before the drop out my traffic was coming from a downlink station in Bulgaria, on an IP on AS14593 Traceroute from "the internet" back to that IP reaches AS14593 just fine, and my endpoint doesn't get beyond the first hop of the local starlink router. Whatever it is, it doesn't look like a peering problem
https://mtr.ping.pe ftw for MTR from "the internet" ? :)
One of the promises of starlink was it would stay in space as long as possible before being downlinked, giving far lower latency, alas that hasn't happened yet, and traffic will run thousands of miles in the wrong direction before being downlinked. For example from one location to another I have 360ms via Starlink but just 200ms rtt via local provision (5g p2p wireless then optical). On another it used to downlink in Lagos, but now it downlinks in Nairobi, meaning traffic to Lagos routes Nairobi -> Marseille -> Lagos, taking far longer than it used to. A shame really.

Donetsk and Lugansk are both sanctioned too I believe.

How would you host a status page on Starlink? Are there web servers that are only connected to a satellite connection in house or something? Or is this just speculation that's how their marketing website works.
Starlink still has infrastructure outside the satellites to run normal company stuff. If they screwed up something in their core routing system, or DNS, etc it could affect everything.
Curious as to what could cause a global outage like that. The system consists of birds in the air and individual ground stations. There's no big choke point that I'm aware of that could cause the whole shebang to go dark. Am I missing something here?
A bad configuration pushed to network
For most large businesses, 90%+ of major network events are caused by internally-driven network config changes.
Depending on how far along the business is towards automation, a proportion of the 90% can be attributed to a human going “off script” - I.e.: making a change that had not been reviewed.
Recently, I’ve noticed that nothing hits the top spot as quickly as anything negative about Elon.
Maybe very briefly before it get flagged

The Russians use Starlink too, saw a video on Kiev Independent that had a Ukranian drone team take out a Starlink dish atop a Russian bunker.

So, if (just spitballing here) Russia were to have wanted to take out Starlink in order to handicap Ukrainian operations, and they didn't want to do something as visible as actually taking out the satellites, what would be the most likely way for them to have done it? And how would we be able to check if that's what happened? No idea if this is plausible at all, just raising the question for anyone who knows more abo…
Starlink has been supporting Russia over Ukraine (congressional investigation into this). So I would bet against Russia, but you never know. Could be rouge. Anonymous has promised in the past to mess with Musk... could be that. Well funded and some crazy good hackers.
https://radar.cloudflare.com/as14593?dateRange=1d shows a sharp drop in traffic, but no BGP changes before the drop. We can see BGP changes after the drop, so maybe some datacenter/control plane thing.

I wondered how much energy could pass through some area 1000 miles away from the explosion, so I made some rough calculations. Assumption: all energy of the nuclear explosion is radiation uniform in every direction. The energy E would be spreading in a sphere with area 4*pi*R^2. Area A being a part of that sphere would capture E*A/(4*pi*R^2) of energy. So with: energy E = 209 PJ (Tsar bomba for an extreme example) ar…
Radiation is measured in gray, which is 1 J absorbed by 1 kg. I can't find the conversion between flux to absorbed dose. 5 gray is fatal. If even a fraction of that energy is absorbed, it would be fatal. I found that satellites get 100-1000 rad per year. Getting that much in a moment would cause problems.
It's measured in a lot of different ways depending on the need, and the unit "sievert" is Gy times a conversion factor that depends on the kind of radiation (for equivalent dose) and which body parts (for effective dose): https://en.wikipedia.org/wiki/Sievert#Radiation_type_weighti...
But also, beta radiation (electrons) will be stopped by a thin sheet of tinfoil, while alpha radiation (helium-4 nuclei) by paper or the outer layer of dead skin on your body and therefore only matters if you eat a source of it, and a significant fraction of any gamma radiation you're exposed to will pass right through you without getting absorbed.
