From 12:59 PM PST until 2:34 PM PST on February 21, 2022, some users were unable to send messages in Slack due to a code change malfunctioning.
Although reverting the change resolved the problem for the impacted users, a corollary issue with similar symptoms surfaced two hours later at 4:34 PM PST and was tracked on our status site under the title, "Some customers may be unable to connect or send messages". We determined this to be a byproduct of the same root cause and remediated the issue shortly thereafter.
5:46 PM PST
We have confirmed that the fix resolves the issue that customers encountered when trying to type and send messages. Customers would not be affected going forward.
3:01 PM PST
We are investigating an issue where some customers are unable to type and send messages in Slack and have since implemented a quick fix.
Customers who are experiencing related errors should try to reload by hitting Cmd + Shift + R on Mac, or Ctl + Shift + R on Windows and Linux.
2:45 PM PST
On February 21, 2022 from 4:34 PM PST to 5:32 PM PST, some customers may not have been able to connect to Slack or send messages. This manifested as an error code within Slack.
A code change inadvertently caused a conflict in the desktop app and web client, preventing a small number of customers from sending messages. We reverted the change, resolving the issue for all affected customers.
10:09 PM PST
We have restored full functionality, and all customers should be able to connect and send messages as normal.
Apologies again for the disruption to your work. We'll be back with an issue summary soon.
6:48 PM PST
Customers should be able to connect to Slack and send messages once again. Please refresh Slack with Cmd/Ctrl + Shift + R to fetch the fix.
We're still monitoring the situation, and we'll report back as soon as the issue is fully resolved or we have news to share. Thank you for holding tight.
6:10 PM PST
We're seeing some improvements, but we're still working to fully resolve this.
We'll share another update in 30 minutes.
5:31 PM PST
Some customers may be unable to connect to Slack or send messages. We are investigating and we're very sorry for the disruption.
