I am genuinely surprised that Slack wasn't ready for people to come back from holiday, to view increased queues of unread messages, to have to manually login vs. having auth tokens or cookies, etc. Either that, or they had a cosmically coincidental outage on a really bad Monday to have it. It's bad enough team comms go over Slack so much now, at least we have email fallback. What scares me is for the teams that use S…

I have always had this fantasy thinking of what happens when outages of one of these major service never come back online i.e. in this outage Slack loses info of all the accounts, users, messages etc.

How would people react? What would engineers do to recover? I always found that idea fascinating.

Imagine Google saying tomorrow that they lost all the accounts and emails. What kind of impact the world will have?

Which AZ?

Availability zones are unique for each account. So my zone A could be your zone C, for example.

I never knew this, but I think it makes sense. Is there any documentation that explains why this is the case? I suspect it is to distribute bias to the first option, but I'd love to read about it.

[edit] Nevermind, I just needed the right combination of terms to find it: https://docs.aws.amazon.com/ram/latest/userguide/working-wit...

And there we have it: Relying on big companies sucks. It's great as long as it works. Once a system breaks thousands, or even millions, of businesses suffer. (Of course they are also beneficial and a private server can also crash at any time + I don't wanna blame Slack, but we always have to keep this in mind).

Notion is sluggish as well. That combined with the reports of HN potentially being slow, is there some larger network issue at play affecting a region of servers, potentially?

My feeling is some common infrastructure is failing or flailing, like some part of AWS, or some backbone provider. Too many flaky things going on at the same time to be independent failures.

Having been in this situation before, with a totally-down-and-not-coming-back-up outage of a payments system, I really feel for their incident response team.

I'll take this moment to remind everyone of their human tendency to read meaning into random events. There's no evidence to suggest New Year traffic has caused this, and outages like this can happen in spite of professional and competent preparation.

Hugops for their team, I hope they get it back soon.

Lever has been down for about the same amount of time as well (job recruiting platform).

Interestingly their uptime for the quarter is still 100% despite a full-red dashboard. I wonder if that's something that is calculated only after an outage is resolved

Well until the issue is resolved you can't know how long you've been down for, so you can't actually update the uptime.

Why not? It could be updated second by second automatically if they wanted to.

Probably not a priority though.
