I add the following as evidence of premeditation / conspiracy:

“I think Trump is going to run again in 2024,” he [Vance] said. “I think that what Trump should do, if I was giving him one piece of advice: Fire every single midlevel bureaucrat, every civil servant in the administrative state, replace them with our people.”

“And when the courts stop you,” he went on, “stand before the country, and say—” he quoted Andrew Jackson, giving a challenge to the entire constitutional order—“the chief justice has made his ruling. Now let him enforce it.”

This is a description, essentially, of a coup.

“We are in a late republican period,” Vance said later, evoking the common New Right view of America as Rome awaiting its Caesar. “If we’re going to push back against it, we’re going to have to get pretty wild, and pretty far out there, and go in directions that a lot of conservatives right now are uncomfortable with.”

“Indeed,” Murphy said. “Among some of my circle, the phrase ‘extra-constitutional’ has come up quite a bit.”

Historical note: as far as I understand, president Jackson ignored the Supreme Court in a case of Georgia taking Cherokee lands. Since the state also ignored, the court failed to enforce its ruling.

As far as I know (I’m also on the EU side of the pond) - they are now obligated to delete anything they downloaded.

Experiments of frequency steering are scheduled until evening. There is a new frequency reserve market and participants need to test out their systems (synchronous compensators, battery banks, etc). So for a known time, frequency will be driven low (and response measured), and then frequency will be driven high, and response measured.

Local perspective: seems to be going smoothly.

Some people were appropriately concerned, but some were a bit too worried (and I’ve had to explain power grid basics to folks who depend on electrcity, but know nothing). If one writes an article saying some lines will be disconnected, some folks automatically assume it’s a power cut. :) Perhaps a lesson about journalists needing to use simple and clear wording if the matter needs to be understood by everyone.

The biggest risk that was taken into account was risk of well-timed sabotage, so more important installations are better guarded for the transition period.

Since Ukraine did it’s synchronization with the European grid while under fire, and also managed - I think that nothing worth mentioning will happen here.

As a minimum, this will slow down the biggest data breach in US history.

In the best case, those who organized the data breach could find themselves facing some charges.
