"vote backlog" is an interesting metric. Does anybody know how the vote counting system works?

#22Does anyone know why Reddit seems to be alone among the world’s most popular sites in having so many outages and frequent periods of slowness? I’ve been on it for more than a decade and its unreliability has been fairly constant. Is the engineering team more resource constrained than others or held back by unusual amounts of legacy code, or is it simply confirmation bias resulting from earlier experiences?
Outages are definitely less common than they used to be. But I would guess that reddit is one of the most popular sites on the internet because it's basically like an anonymous(ish) facebook with content guaranteed to be popular with the majority (by design).
They've also made major efforts to keep the site socially sane for the majority of users (for better or worse, IMO generally better) with their moderation model.
Whether or not it's a great site technically is irrelevant. It's something people want and something I keep coming back to because there's no equivalent when it comes to niche communities.

I believe comments, posts, and votes are placed into a queue and later (seconds usually) committed to the database. They're not visible to the public until they're committed (but they make the UI act like it's already there for the poster themselves). Just a guess from my observations though.

#24Anyone willing to put a price on 1 hour and 14 minutes of Reddit downtime? I would guess this cost less than a $1,000,000 USD but more than $100,000.
According to [], they had $119M revenue in 2019. That's about $14k/h. [] https://techcrunch.com/2019/12/04/reddits-monthly-active-use...

Pretty standard pattern. Facebook does it as well.

From AMA (ask [Reddit sysadmins] anything) announcement 2019/09/19 https://old.reddit.com/r/sysadmin/comments/9ver7h/14nov_redd... "I can answer this! According to various sources (mainly, complaints on the redesign subreddit), the new.reddit interface is a lot less tolerant of timeouts and delays. Old.reddit was much more relaxed and would wait longer before throwing up errors (like logouts and such), but new.reddit…
Wow, I didn't know there was actually more to dislike about "new" reddit.

#28Reddit is hosted on AWS. Are they using Fastly as their CDN because it's cheaper than AWS CloudFront CDN?

Even if it were truely the reason (it's just someone uninvolved who saw a lot of complaints about the new interface) it doesn't explain the rest of the decade where there was no "new interface" and it was still a meme that Reddit was constantly down.

#30I am convinced that Reddit's status page underreports outages, there are a lot of times I can't access the site for 15min but it never shows up on here. (And I don't even visit it that often.) I think they're the major company with the fewest 9s of uptime.
> I am convinced that Reddit's status page underreports outages
If they are like every other major company out there, status page reports are a function of a manager or PM judgement call, not the output of a monitoring system.
