2/ Here's a simple explanation for what took down @Facebook that some of us can relate to — from a tech person.
Facebook changed its permissions this morning, and the change accidentally disallowed Facebook's networking computers from finding & talking to each other.
Oops.
3/ The change likely propagated to Facebook's servers automatically.
But here's the catastrophe: You can't propagate the *fix* to the permissions automatically.
Because the computers you're fixing aren't allowed to find & talk to each other.
Gotta input permissions manually.
4/ Ouch.
With apologies for oversimplification of very complicated technology.
But: Here we are 5 hours after outage of one of the largest internet utilities.
I just wanted to understand how something like that could possibly happen, given FB's resources & technical expertise.

For the 2021 holiday season, these 5 big employers have announced hiring goals:
• FedEx: 90,000 employees (v. 70,000 in 2020)
• UPS: 100,000 (same)
• Amazon: 120,000 (v. 100,000)
• Target: 100,000 (v. 130,000)
• Walmart: 20,000 (same)
That's 430,000 at 5 companies.
2/ As an incentive, UPS has started a program to offer you a job within 30 minutes of applying, if you qualify. (A huge incentive in the world of online job applications, where you apply and then…never hear anything.)
3/ The US has 10.9 million open jobs right now.
How will WMT, TGT, UPS, FDX, AMZN find & hire people for tough, high-pressure jobs, with modest pay — at this moment?
