The Speed Limit on Survival

A hundred miles an hour. On a British motorway, it’s roughly the point where a traffic officer stops reaching for the fixed penalty pad and starts thinking about a court date. As of Tuesday night, it’s also the speed above which a Ukrainian drone, the kind sent up to knock Russian attack drones out of the sky before they reach a city, stops being able to talk to the satellite guiding it. Nobody announced it. Nobody sent a memo. The terminals simply went quiet mid-flight, missions failed, and the people on the ground found out the way you find out your bank has quietly changed its terms… by having your card declined at the worst possible moment.

I have spent a good chunk of my life around one deceptively boring question, which is who holds the keys. In the RAF Police, and later in senior security management, the job was rarely the dramatic stuff people imagine. It was access. Who gets through which door, on whose authority, with what notice, and whose signature sits at the bottom of the page when it all goes wrong. So when I read that a country fighting for its existence had its battlefield connectivity throttled overnight, and that the two most powerful men who could have done it appeared to be pointing at each other, I didn’t feel outrage so much as a deep professional twitch. Because this isn’t really a story about satellites. It’s a story about leverage, and about what we are now prepared to file under “reasonable”.

What actually happened

The facts, as far as anyone outside a server room in Texas or an office in Washington can establish them, go like this. Late on Tuesday 13 October, Ukrainian units using StarShield, the military-grade sibling of SpaceX’s Starlink network, found their terminals losing connection whenever they moved faster than roughly 160 km/h. Serhii Beskrestnov, the defence technology adviser to President Zelensky, who goes by the call sign “Flash”, confirmed it on Telegram the next morning. Ukraine’s forces had been given no warning, several missions had been disrupted, and in his view the timing “cannot be a coincidence”. Ordinary commercial Starlink terminals, reportedly, carried on working just fine. It was only the military package, and only at the speeds that matter for drones, that hit the wall.

That detail matters more than it first appears. Ukraine leans on satellite links to guide its drones, both the ones it sends forward and the interceptors it launches against Russia’s jet-powered Shaheds before they reach Kyiv. A speed cap of 100 mph doesn’t inconvenience a soldier checking messages in a trench. It surgically removes the fast-moving end of the toolkit, offensive and defensive alike, while leaving everything else looking normal.

Elon Musk’s response was quick and, on its face, a clean pair of hands. StarShield, he said, is owned and controlled by the US government, and any limits on speed or usage are set by the US military and “ultimately POTUS”. By Wednesday evening, Ukraine’s former defence minister Mykhailo Fedorov was saying connectivity up to that speed was being restored and publicly asking for the cap to go altogether, while Zelensky’s office told NBC the limits were still in place. At the time of writing, nobody in Washington has stood up and claimed the decision. Meanwhile, Russia did what Russia does. Strikes on power plants around Kyiv and in Kharkiv killed people and left hundreds of thousands without electricity, and for the second time that week, Ukraine says its allies gave it no advance warning of incoming ballistic missiles. The White House insists intelligence sharing continues.

The reasoning, laid out on the table

To understand why Kyiv smelled a rat, you have to look at the fortnight that came before it, because the logic being offered to Ukraine is worth examining slowly. For months Ukraine has been hitting Russian oil refineries with long-range drones, and by Putin’s own reckoning those strikes have cost Russia around one per cent of its GDP. That is not a nuisance. That is a war economy bleeding. The American President’s argument is that these strikes push up global fuel prices, and with diesel expensive at the pump and the midterms weeks away, he has told Zelensky to stop. Over the weekend Musk added his own two pennies’ worth, posting that “Zelensky has gone too far”. Then came the announcement of an “energy ceasefire”, which Ukraine said it would honour if Russia did the same. By most reports, Ukraine has held its fire on the refineries since. Russia, on the other hand, went straight back to bombing Ukraine’s grid.

Now hold that up to the light alongside one more fact. Only days earlier, the same administration announced a deal for Russia to release hundreds of thousands of tonnes of diesel onto the world market, with US sanctions on Russian diesel relaxed until April 2027, barely a month after the President signed a sweeping new sanctions law aimed at exactly that revenue. Senators from both parties called it a financial lifeline for Putin. Zelensky called it a gift. And fuel prices, it’s worth remembering, have plenty of other drivers this year, not least the US-led war with Iran and the disruption around the Strait of Hormuz.

So the reasoning, stripped of its suit and tie, runs something like this. Your self-defence is raising our prices. Please stop damaging the enemy’s fuel industry, because we’ve just agreed to buy its fuel. And if the enemy keeps bombing your power stations in the meantime, well, that’s regrettable, but we have an election. I’m not a diplomat and never pretended to be, but I spent long enough watching how decisions get dressed up to recognise one being dressed up now. This isn’t a peace policy. It’s a supply chain with a press release attached, and it quietly converts a victim’s right to fight back into a consumer externality… a line item on somebody else’s petrol receipt.

Pass the parcel

Here is where my old training starts to itch properly. When something goes wrong in any well-run organisation, the first question is always the same: whose decision was it? Not whose fault; that comes later. Whose decision. And right now the answer on offer is a game of pass the parcel. Musk says it’s the US government’s system and the President’s call. The White House, as I write, hasn’t said a word either way. Ukraine’s officials, who are the only ones actually standing in the blast radius, are left to guess, and a senior Ukrainian MP has said openly that it looks like blackmail designed to stop the refinery strikes.

You don’t have to take sides on that to see the problem. If Musk is right, then the United States government quietly degraded an ally’s air defence in the middle of a Russian bombing campaign, without telling them, while publicly claiming to have brokered a ceasefire. If Musk is wrong, then a private citizen did it and blamed the government. Neither version is comforting, and the fact that we genuinely don’t know which is the more unsettling part. Musk has said before that Starlink would never be used as a bargaining chip, even when he disagrees with Ukrainian policy. History makes that harder to take on trust. Walter Isaacson’s biography described him refusing to let Ukraine use Starlink for an attack near Crimea in 2022, and Reuters later reported he ordered coverage cut over areas of a Ukrainian counteroffensive that autumn, which SpaceX disputed.

And notice the shape of the instrument this time. Not a switch-off, which would be loud, obvious and politically radioactive. A speed limit. Commercial service untouched, military service mostly working, and only the bit that turns a drone into a weapon or a shield quietly capped. It is the kind of measure you design when you want an effect without a headline, and deniability without a lie. In my old line of work, we had a word for an action engineered so nobody has to own it. We called it a problem.

What the memos taught me

After the RAF, when I was running security operations in civvy street, the staff had a nickname for me. Mr Memo. I earned it honestly, by putting every change of procedure, every new restriction and every altered access arrangement into an open memo that people had to sign to say they’d read it. It drove some of them up the wall. It was slow, it was fussy, and it felt like bureaucracy for its own sake. Then, more than once, something went sideways, and the same Directors who had rolled their eyes at the paperwork were suddenly very glad of it, because it proved who had been told what, and when, and by whom.

I didn’t do it because I loved paper. I did it because I’d learned that notice is not a courtesy. Notice is the thing that separates a decision from an ambush. If you change somebody’s access, you tell them before you do it, you tell them why, and you put your name at the bottom. That’s not a lofty principle from a philosophy seminar. It’s the bare minimum standard of a halfway decent security manager, and I find it slightly dizzying that it apparently sits above the pay grade of the people running the most consequential communications network on the planet.

There’s a family thread here too. My father served in the Royal Signals and rose to Warrant Officer Class One, and I grew up in a service household, in Britain, Germany and Norway, during the long grey stand-off of the Cold War. Signals was never “the IT department”. It was the nervous system. Cut it, or slow it, and the body still looks alive for a while, but it can no longer feel where the danger is coming from. Every military family I knew understood, without needing it spelt out, that whoever controls your communications has a hand on your throat, which is precisely why you don’t hand that control to someone whose priorities might change with the opinion polls.

The line Musk drew himself

In the same breath as passing responsibility to the President, Musk drew a line of his own. Commercial Starlink, he said, is for civilian or defensive use only and can’t be used for offensive military action, because that wouldn’t be appropriate for a commercial company. Fine. Let’s take that at face value, because it’s actually a respectable ethical position. A company can reasonably decide it doesn’t want its product used to blow things up. Strictly speaking, he drew that line around the commercial service rather than StarShield, but it’s still the fairest yardstick we’ve been offered for judging what just happened.

But look at what a 100 mph cap actually catches. An interceptor drone climbing to meet a Shahed before it ploughs into a block of flats in Kyiv is about as defensive as military hardware gets. It is the satellite-age equivalent of a sandbag. A speed limit can’t tell the difference between that drone and one heading for a refinery in Russia. It catches both. So if the restriction was driven by ethics, the instrument is clumsy to the point of being self-defeating, because it degrades exactly the kind of protective use the stated principle claims to permit. If it was driven by leverage, on the other hand, the instrument is close to perfect. It hurts precisely where Ukraine is most exposed, at precisely the moment Russia is pounding its grid, and it lands the week Kyiv is being leaned on to stop its own strikes.

That, for me, is the heart of the ethical problem. You can argue about whether Ukraine should be hitting Russian refineries. Reasonable people do. What I can’t find a decent argument for is responding to that disagreement by throttling the shield instead of the sword. When the pressure point you choose is a defending population’s ability to stop missiles reaching its cities, you are no longer having a policy debate. You are using civilians as the lever.

The case for the other side

I’ve no interest in writing the kind of piece where the other side exists only to be knocked down, so here it is, as fairly as I can put it. A government that supplies a military system is entitled to set terms for its use. The United States is not Ukraine; its taxpayers fund an enormous share of this war, and its President answers to American voters, not Ukrainian ones. If Washington believes long-range strikes deep into Russia risk escalation, or are wrecking a fragile negotiation, then restricting the tools that make those strikes possible is a legitimate lever of policy rather than a betrayal. Refinery strikes genuinely do move markets. And a cap is not a cut-off; by Wednesday night Ukraine’s own former defence minister was thanking Musk and reporting partial restoration.

There’s a harder point too, and Europe in particular should sit with it. Nobody forced Ukraine, or the rest of us, to build so much of our security on a single privately owned network run out of one country. That dependency is a policy failure with a lot of fathers, and some of them speak with British and European accents.

I accept most of that. Where it falls apart for me is the method. Terms that are set openly and in advance are policy. You can argue with them, plan around them and build alternatives. Terms that are changed overnight, without notice, in the middle of an air raid, by an authority nobody will publicly name, aren’t policy. They’re coercion that has been designed not to leave fingerprints.

Sovereignty on a subscription

Poland’s foreign minister, Radosław Sikorski, who has clashed with Musk over Starlink more than once, put the European mood in a single jab: “Big man, are you playing politics with your products again?” He followed it with a reminder that Europeans are customers, and customers are watching. It’s a good line, but I think the real lesson is bigger than one man or one company. What happened this week is a demonstration, live and in public, of what it means for a nation’s defence to run on somebody else’s subscription. The terms and conditions can change. They can change overnight. And when they do, there’s no helpline, no notice period and no cooling-off clause, just a drone falling silent at 101 miles an hour.

I live off-grid now, in a cave dwelling in the Spanish hills with a handful of friends, and people sometimes assume that’s a romantic gesture, a bit of rebellion against modern life. It isn’t really. The single most useful thing it has taught me is unglamorous: know which switches are yours. The water you collect is yours. The power you generate is yours. Anything that arrives down a wire or through the sky from someone else is a loan, however permanent it feels, and loans get called in when the lender’s circumstances change. Ukraine is learning that at a cost measured in lives. The rest of Europe, the UK very much included, is watching it happen and, I suspect, quietly checking which of its own switches it actually owns.

I’d like to tell you this ends tidily. Perhaps by the time you read this the cap has been lifted, a statement has been issued, and everyone has agreed it was all a misunderstanding. Perhaps we’ll never find out whose finger was on the button, which is rather the point of a button like that. But the precedent has been set either way. A defending country’s ability to stop missiles reaching its cities was throttled, without warning, in the same week it was being told to stop hurting the economy of the country firing the missiles, by people who were busy buying that country’s diesel. Nobody has signed the memo. Nobody has put their name at the bottom of the page. And I keep coming back to that number. A hundred miles an hour. Fast enough to catch a drone. Apparently not fast enough to catch up with a principal.
