My curiosity is killing me as to what exactly went wrong. And as someone living in The Netherlands I'm also kind of mad at the apparent fragility of this huge chunk of our infrastructure. If this had happened on a work day, it would have been a real national emergency, rather than just a huge national inconvenience. I would appreciate one of those post-outage "what happened" reports like with the AWS and Facebook out…

If it happed on a work day I wonder if peoples pandemic logic would kick in and you would start hearing, "It's not worth closing down the whole economy just because of the risk of a few people dying in a train crash"

My very good guess is that you had a database failure caused by a crypto virus. They will not wish to announce that this was the root cause until A. A plan of action to avoid a future infection can be enumerated. B. They can be certain they will restore the functionality of the trains. The other part of my guess is that they have a SQL db which is stored on /likely/ a windows server instance. I’d even surmise that th…

Well, as long as you're clearly stating _this_ part of your otherwise validated and highly likely pre-post-mortem is speculation...

Isn’t this exactly what the press release states? “ if there is an incident somewhere, the system adjusts itself accordingly. This was not possible due to the failure.”

No, it’s talking about crew scheduling/allocation , not signaling. The signaling system is totally fail safe. Even if that system totally went out, drivers are required to know where all the signals are, and to treat an unlit signal as a red.

What if the failure lit all the signals in green?

Physical infrastructure can be fragile/fail catastrophically, as well. I recall starting a job near Seattle, 40 miles from my home in Olympia, WA and a passenger train derailed onto the highway killing a few people and backing up traffic for days. That was not a pleasant first day! https://en.wikipedia.org/wiki/2017_Washington_train_derailme...

I assume, however, that this didn't ground every single train in the state!

No but the failure caused a halt to all motor traffic on I5 in both directions which is possibly even more catastrophic than stopping the entire train system.

Voting by mail is insecure? This is very troubling.

It's not simply voting by mail, it's voting by mail by not even using official the post office in Romania. I know that you're probably refering to US, but I don't make any comment about it, because I don't live there, so I don't know what really happened in US. In Romania some people found partially burned ballots with only opposition votes next to a garbage bin before the elections ended. The proofs of voter fraud c…

Well that is just an isolated case. There is simply no evidence to support the baseless conspiracy theory that postal voting results in widespread fraud. This has been well established by the experts and journalists.

Most countries (even non EU ones) allow its citizens residing in foreign countries to vote in national elections at its embassies. So Hungarians residing in Netherlands could have been able to vote at Hungarian embassies/consulates in Netherlands (if they made it to the embassy).

Sometimes even local stuff. U.S. states, our provincial government level, have processes in place to account for Americans living abroad to vote in state and local elections. It’s guaranteed by law, I think. Our states handle all voting on behalf of the federal government anyway (registration, voting day operations, counts, all often under the misleadingly named office of a Secretary of State), so it’s a natural cons…

A shocking thing for me is that if you're an American living abroad registered to vote in California you're allowed to vote by email (well technically fax, but there's a DoD email alias you can send your scanned ballot PDF to and someone will print it out and fax it, which counts). Oh, and if you vote any ballot this way other than a write-in for federal offices you might also get a residency audit and have to pay California's personal income tax (which doesn't recognize any US tax treaties). You're not allowed to vote by fax or email if you don't have a non-US address.

My guess for the attacker : conti ransomware group. They've been pretty active since Ukraine war. Last weekend they targeted the central bank of Tunisia

Were the elections illegitimate ? I'm a complete outsider to hungarian politics so I'm not sure if this is hyperbole... but talking about how a dictatorship has been reelected again doesn't make sense to me. Unless elections in Hungary are just theather, and results are just faked like in Syria for example.

It's a relatively free election, there's a strong incumbent bias that undoubtedly helps him win but there's no evidence the entire thing is rigged. Dictators can be popular, the best example is Napoleon.

The government made extra payments to their typical supporters like pensioners and rural areas. Economically strong regions and younger professionals pay the bill and are free to vote against, but they remain a minority.

scheduling hasn't been used for preventing conflicting movements since the 1830s https://en.wikipedia.org/wiki/Railway_signalling#History_of_...

It still sometimes is. There was a big crash in Czech republic recently, where two passenger trains (motor units) collided head on between stations. Some local routes with few trains a day, where there is no longer any track-side staff, operate in a simplified rules (there is a whole code for that). There, the train will arrive to a station and depending on a symbol in the timetable, it will either continue to the ne…

There is also the token-based control of bidirectional travel on single-track, in which physical posession of a token governs permission to enter a track block. Still used in various places.

Why "unsafe"? Isn't safety supposed to be handled at a different abstraction level (in hardware)?

It sounds like it was a crew scheduling issue. So if you implement some manual replacement for the automated system, it's possible that train crews will "time out" before they reach the destination, stranding passengers in the middle of nowhere. Or, will make a tired crew operate the trains, and tired people aren't very good at safety sensitive tasks. There was an incident a few years ago where a LIRR track crew memb…

> It sounds like it was a crew scheduling issue.

I'm not from the NL, but I have travelled there by train. My feeling is that they have very dense traffic, but in a relatively small country most trains don't travel more than 2 hours. That means each driver and each conductor needs to make 4 different trips a day. And because they need breaks they proably switch trains during a working day. If all this planning has been computerized for many years it just means that nobody knows what to do next if the computer screen remains blank. Probably they don't get a printout in the morning like it was some decades ago. No idea how adaptively the system would react during the day dependening on delays and disruptions.

Just guessing, maybe some insider knows more.
