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.

The carrington event knocked out telegraphs all over the world in the 1800s.

That’s the most powerful geomagnetic storm on record. It induced so much current in the telegraph wires that they literally melted.

In the 1800s that wasn’t a huge deal. But if it happened today, billions of dollars of electrical infrastructure could be rendered useless, and stockpiles of replacements are already non existent. It would take years to recover.

But this is not that strong of a storm, so I doubt it’ll do anything but cause some pretty lights and maybe ground a few flights due to communications issues.

And I’m sure any affected areas and satellites will be shutdown for that period to reduce any operational risk.

So less planes falling and more planes delayed.

Same for network communications as items are routed around certain areas or via some methods like fiber vs others.

Planes wouldn't just fall out of the sky anyways lmao. Even if planes lost communications completely they are still operational flying machines. It would just be very difficult to coordinate planes landing at that point. I don't know about the protocols, but I'm sure there exist failsafes to coordinate air traffic in the event of radio communication loss.

True and I didn’t mean to imply it. Went for the hyperbole you tend to see and did a poor job with it after all.
