Rules:

Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.

We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.

All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

I live very close to the border but on the French side, we had a tiny outage of about 1/3 of a second (but long enough to reset routers)... That's probably why.

That's all it takes some times if conditions are bad inside a grid.

This is one of the unfortunate downsides to moving form 'large spinny things' in coal generation to tiny integrated circuits generating the rotational momentum needed in an AC system. We had a similar issue in South Australia in 2016, complete black system after a number of events but of the two biggest preventable causes, one was simply the loss of rotational momentum in the system, in 1995 is used in be close to 10s, in 2016 it was less than .6s

We need to start rethinking the grid for the future, we can't keep coal/gas but we also can't keep a grid completely reliant on momentum for short term ride through.

Why would that require coal though? Wouldn't nuclear power provide the same rotational momentum with the turbines? Wouldn't hydro electric also provide rotational momentum?

Flywheels can give the same momentum.
