Incident

Less than 1% of users are appearing in a huddle after the huddle has ended

Issue summary:
From December 7 at around 8:00 a.m. PST to December 13, 2021 at around 1:49 p.m. PST, some customers experienced issues with calls and huddles.

Following a service provider's outage, stale requests in our database prevented some users from joining new calls and huddles, while stale cached data caused some users to appear active in both.

We manually cleared stale calls and huddles from our backend, restoring functionality and dislodging stuck user statuses.

4:26 PM PST

We believe the issue with users appearing in a huddle after it has ended should now be resolved for all customers. If you continue to have any trouble please try reloading Slack (press Command/Control + Shift + R). You can also reach out to us at feedback@slack.com if the issue persists.

We’re continuing to work towards resolving this issue for the very small number of users who are still impacted. We appreciate your continued patience, and will let you know as soon as we have another update to share.

While we have deployed a fix, some customers may continue to appear in a huddle once a huddle has ended. We are continuing to investigate this issue and will keep you updated.

We've deployed a fix, and customers should no longer be experiencing this issue. If you continue to have any trouble, please let us know via feedback@slack.com

10:28 PM PST

We are still investigating the huddles issue that's causing the huddles status to remain as well as the inability to join new huddles.

Some users may be unable to initiate new huddles in addition to appearing on previous huddles after they have left. We're investigating this issue and we thank you for your continued patience.

Some users may appear to still be on a huddle once the huddle has ended. We’re investigating the issue and will be back with an update shortly. Thank you for your patience.
