API pricing protests caused Reddit to crash for 3 hours

Thousands of subreddits going dark broke Reddit's website, mobile app.

@arstechnica Good but …. Why would it crash the site?
@tk_uk @arstechnica Guess that reddit servers weren't exactly prepared for such massive change of subreddit states.
@tk_uk @arstechnica guessing the subreddit is private message all goes to one endpoint and that got overloaded with requests when the super popular subreddit’s went dark
@dreamstride @tk_uk @arstechnica one would assume that their super efficient app was taking care of this already. Maybe it’s all the people trying to access from Apollo /s
@tk_uk @arstechnica I’d love to read that postmortem
@tk_uk
@arstechnica

Reminds me of the local mass transit system each time they hike rates – it's always one of "there's too many customers, we need to raise rates to pay for capacity" or "there's not enough passengers, we need to raise rates to offset the revenue loss".

But, yeah: how does curtailed traffic cause the site to fall over??

@tk_uk @arstechnica

I'm asking the same question.
This answer is what corporate gives support when they can't admit the truth.

"A significant number of subreddits shifting to private caused some expected stability issues, and we’ve been working on resolving the anticipated issue."

@tk_uk
@arstechnica I think because it's like changing permissions for thousands/millions of users and all related posts. Servers went mad (and their bills too probably)
