    GREAT EXPLANATION! I think they were bitten by their own pet. Everything created by facebook for facebook, and it was all prone to 2 bugs, wow!

    I don't think it was human error. I feel they strategically shut down the entire network to clean up all the evidence and crap that the whistler blower outlined in the 60 hour interview.

    Each minute of the video is so informative 😁it's super interesting to see how these things happened in such a big infrastructure (best part for me 😃-> 8-10 hours is super busy for FB engineers ;)😅

    I watched the video till the end, but I have a lot many questions in my mind.

    1. Firstly, if it was really that simple to give a wrong command and bring the entire system down, then this would've happened on a regular basis. If the audit system had such a critical bug, would Facebook really overlook that?

    I watched this till the end and it was absolutely interesting. Well delivered 👌🏼
