> A significant number of subreddits shifting to private caused some expected stability issues, and we’ve been working on resolving the anticipated issue,” Calling bullshit on that one. If they had expected stability issues, and knew exactly which subreddits will go private and when, how is it possible they had so much "anticipated issues"?

> and knew exactly which subreddits will go private and when

As someone who is close to a reddit mod, they did not know which subs would go private

The world has finite resources... such as man-hours.

Such a critical moment for the future of the company (mass boycott after controversial changes, presumably on the path to IPO; they really don't need any more bad publicity) should be an all hands on deck situation. Again, they've had advanced notice, and knew the full list of subreddits. They should have prepared better.

It'd be funny if the engineers at reddit decided now was a good time to upgrade postgres or do some other kind of scheduled maintenance, and just not worry about downtime because the blackout is on anyway.

Or rolling out the big blackout override switch

It seems that Reddit will go down like Digg did.

Unfortunately, I've been hearing this for like a decade and it doesn't seem to ever happen.

Digg.com’s implosion was so dramatic because Reddit was there to immediately start serving the same users just about the same thing. There are obviously plenty of other things Reddit users can do with their time, but there isn’t a monolith solution waiting in the wings to very closely replace Reddit with almost the exact same thing. Its destruction will be much more prolonged.

The main reason why reddit works as a platform is because its mods and subreddit regulars do a lot of unpaid work. Where is reddit going to find enough people to work for free on such short notice?

They don't have to be good mods. There's precedent for a handful of mods to moderate a huge swath of subreddits.

Not without third-party tools, there isn’t. Lol

That's more expensive than free mods.

I have not read a reddit devblog or anything like that. My guess is they are doing some kind of caching of posts via elasticsearch/redis or something similar. It must depend on the privacy settings of a sub. So when 1000 subs go private, they potentially had to update hundreds of millions of comments. Anyone else have a theory?

That makes sense to me. It would be one variant of a larger theory of "a subreddit going private is an expensive process that is poorly optimized because it's normally so rare". Another variant would be that clicking the "go private" button might do something like start a huge cascade of queries/calls to mutate the status of individual posts and comments (and possibly hence also trigger the massive cache invalidation…

AKA why you should normalize your data models.
