The fewer resources we dedicate to grid resilience and modernization, the harder black starts become. And as grids get more complex and interdependent, recovering from total failure becomes exponentially harder. A rare but sobering opportunity to reflect on something we usually take for granted: electricity. We live in societies where everything depends on the grid — from logistics and healthcare to communications an…

Yeah, this is the turkey’s dilemma - life on a farm is a lot better than life in the wild for 51 out of the 52 weeks of the year. Most of our modern economy and systems are built to reduce redundancy and buffers - ever since the era of “just in time” manufacturing, we’ve done our best to strip out any “fat” from our systems to reduce costs. Consequently, any time we face anything but the most idealized conditions, th…

This sounds big enough to require a black start. Unfortunately, those are slow and difficult. If an entire nation trips offline then every generator station disconnects itself from the grid and the grid itself snaps apart into islands. To bring it back you have to disconnect consumer loads and then re-energize a small set of plants that have dedicated black start capability. Thermal plants require energy to start up…

Spain is part of the largest interconnected grid in the world: https://en.wikipedia.org/wiki/Continental_Europe_Synchronous...

Does this really qualify as "black start" when they can rely on the bigger EU grid?

Would this be relevant here? Spain is connected to the French grid, and probably also Morocco. The entire EU runs on one synchronised grid so from that perspective a single 'province' went offline, not the grid.

The continental part of the EU runs on one synchronized grid. The Nordics (except half of Denmark and, uh, Iceland, Greenland etc) runs on a separate synchronized grid.

To remember: in the early hours of this morning there was a huge purchase/transfer of monero that increased the price +30% (highly unusual) and a few hours later before lunch time we see Iberia disconnected from the grid. Monero is the favorite payment coin when ordering real cyber attacks.

Related talk in Berlin 5 months ago detailing how to shutdown energy grids using only radio waves: https://media.ccc.de/v/38c3-blinkencity-radio-controlling-st...

Not really relevant, but the talk was in Hamburg

I'm going with: never attribute to malice what can be explained by ... an incredibly complex system that can fall over even if no-one's being stupid. I would want very strong evidence before I believe this is an attack. There is precedent for major power outages, a huge majority of which are not malicious: https://en.wikipedia.org/wiki/List_of_major_power_outages I remember the day when the Swiss railway power networ…

“induced atmospheric vibration” on 400KV lines is the current theory

I would _love_ to understand more about how this atmospheric state impacted the vibration of power lines. Sounds exotic.

For offline messaging over Bluetooth/Wi-Fi without internet or central infrastructure, I saw these recommended by ChatGPT Deep research and they seem current: Bridgefy (Android & iOS) – direct Bluetooth mesh within ~100 m, instant one-to-one & group chat, <1 min install. Berty (Android & iOS) – E2E-encrypted over Bluetooth/Wi-Fi; Briar (Android) – E2E-encrypted over Bluetooth/Wi-Fi with Tor fallback. Manyverse (Andro…

Whoever downvoted, a comment explaining why would be nice, when the cell tower generators are out, and there is only phone battery left, offline communication options could be useful, I'm glad I'm not in that position right now.

Seems like some people are not interested in honest and useful feedback because this got downvoted too! I thought it made clear points about an important topic. Well, whoever sees fit to do this, I hope you get whatever it is you want.

Earlier quoted context omitted.

Let me introduce you to the physical receipt block which is made of paper and can be filled up with a pen, and what is still often used in, for example, Christmas markets.

Many countries require receipts to be sent to the tax services instantly. In many cases a long enough power cut (days) would render all transactions illegal (And in many cases you cannot legally pay large amounts of money in cash, it has to be electronic)

Most governments are not as stupid as the anti-government wingnuts would have you believe. They will not prosecute you for taking transactions non-electronically during a power outage.

I was going to say something similar. I live in Portugal and I've heard a lot of panic/fear mongering, mainly from the techies in the co-working space I was working on and expats. (apologies for singling out these specific groups of people - my point is that it might be worth to put down news sources like xitter, and read AP/translated local Portuguese news)

"xitter" in Portugese would be pronounced as "shee-tehr", right?

That's how some have been pronouncing it in English, too.
