Are we going to start a betting pool as to why? I put $20 on DDoS, but I'm hedging $5 that someone spilled their drink on something important and quickly got out of there before anyone noticed.

Wouldn't DDoS be incredibly hard to pull off given YouTubes vast resources? I mean they generate so much traffic all the time and serve so many requests a second I don't know if botnets of that size exist. Anyone here more knowledgeable?

I believe you can still bring it down through a distributed amplification attack. Refer to Google for more info.

Hey! Conspiracy time! Maybe it's an inner splinter rogue group within Google that's been secretly hating on a Youtube team and decided to get the ultimate payback for like... not inviting them to a lan party...or something...aliens ate all the cheesey poofs.

It's crab people for sure.

I'm not saying it's aliens, but...

Unrelated, but on a recent network outage ( https://status.cloud.google.com/incident/cloud-networking/18... ): The incident occurred while Google's network operations team was replacing the routers that link us-central1-c to Google's backbone that connects to the public internet. Google engineers paused the router replacement process after determining that additional cabling would be required to complete the process…

Spanner and Storage at least are region-wide, so a single AZ going down shouldn’t affect customers on those products.

Medium sized regional AS here: I am looking at a fairly large drop in IX traffic charts for our ports that face the IX, updated every 60s, which directly corresponds in time with the beginning of the Youtube outage. (We are not big enough to have a direct, dedicated peering session with the Google/Youtube AS). At any given time of day 4pm-11pm a huge percent of our traffic is Youtube (or netflix, or amazon video, or…

IX?

What is an AS

From the wikipedia article: https://en.wikipedia.org/wiki/Autonomous_system_(Internet)

    ...an autonomous system *(AS)* is a collection of
    connected Internet Protocol *(IP)* routing prefixes
    under the control of one or more network operators on
    behalf of a single administrative entity or domain that
    presents a common, clearly defined routing policy to the
    Internet.

My vote: Bad configuration got pushed.

I thought they had all sorts of crazy canary deployment processes that will automatically stop/rollback the deployment if the failure metrics start increasing?

Ran out of canaries?

Well, could be an unforeseeable-wack-crazy-bug. Can't plan for every possible failure.
