Slack Running Slow / Hanging?

For me the status page says "Customers may have trouble loading messages or connecting to Slack"

The status page has now been updated [0]:

> Customers may have trouble loading channels or connecting to Slack at this time. Our team is investigating and we will follow up with more information as soon as we have it. We apologize for any disruption caused.

now they've upgraded from incident to outage and impact for all services.

We're continuing to investigate connection issues for customers, and have upgraded the incident on our side to reflect an outage in service. All hands are on deck on our end to further investigate. We'll be back in a half hour to keep you posted.

- 1m ago, completely halted. Can't load desktop application, Android app is unresponsive.

for a brief period, I had an interesting glitch where my messages were reordered on my screen (A,B to B,A and back within a few milliseconds)

The incident appears to be acknowledged now: https://status.slack.com/2021-01/9ecc1bc75347b6d1

DownDetector [1] is sometimes a better status page.

Was my first though too, really looks like they scale down based on the average of the last 2 weeks, but obviously this last 2 weeks would have been extremely low.

ahhh this is a much better theory than mine: my first thought was the lifting of a holiday deploy freeze.

I hope that's the issue.

Hmm so 2021 is the year they switch to k8s for fast scale up and multiple engineers get a promo out of it?

You'd think at their size of their team they'd understand that they would need to scale back up in anticipation of the post holiday return to work.

Slack has the most outages of any major company.

My thought was everyones local cache was expired and it's re-syncing everyone. Supposedly they run vitess for mysql sharding, and that could mean they're getting slammed by a lot of scatter or cross shard queries they can normally handle.

Customers may experience issues connecting to Slack to loading channels at this time. Our team is on the case and we will keep you posted. Apologies for any disruption.

I have to rely on Teams now, the horror. God forbid I have to start using the telephone next!

On a more serious note, downtime is not that bad, it probably allows me to focus without interruption for a bit, but will quickly create problems. Being the first day of the year, there is a lot of quarterly planning going on and many colleagues are reaching out for this. There is also the flurry of typical support queries after a break of nearly two weeks, at least for most.

The status page of our app has failed due to so many reasons, eventually I just let the status page perform a few tasks a user would do, and undo them after that.

Not visiting a special status url, but basically running an e2e test suite on production.

It runs every 5 minutes.

Email?

We have a Discord that's already setup for voice calls, so people organically go there when Slack goes down.

That's what I was wondering. Its shows all green. EDIT: Finally some update. https://status.slack.com/2021-01/9ecc1bc75347b6d1
