A small percentage of users are experiencing issues with Slack.

On May 23, 2023 between 8:38 AM PDT and 9:44 AM PDT some users were unable to send and edit messages, load threads, join channels and create group DMs.

Our investigation uncovered that a recent code change we made had caused an overwhelming impact on our databases. We rolled this change back and temporarily redirected user traffic as our databases recovered. Once we rolled back the change and our databases were in a healthier state, the issue became resolved for impacted users.

We will continue to implement new ways to detect issues like this early-on.

Thank you for your patience while we investigated and resolved the issue.

Users reporting trouble loading profile information

Issue summary:
On May 23, 2023 from 5:30 PM PDT to around 8:15 PM PDT, some customers may have experienced blank profile pictures, display names, channel names, and emoji in Slack.

A code change inadvertently altered the firewall rules for some of our regional servers, preventing the Slack clients connected to these regions from loading profile and channel elements as expected.

As an immediate mitigation step, we stopped the code change from rolling out any further, and pushed all traffic from the affected servers to other regions. This resolved the issue for impacted customers.

We then reverted the code change and manually restored the correct firewall rules on the affected servers. Once the correct rules were back in place, we reintroduced traffic to these regions, fully resolving the issue.

11:34 PM PST

We’ve released a fix and all impacted features are up and running once again. If you’re still encountering any trouble, please reload Slack using Command + Shift + R (Mac) or Ctrl + Shift + R (Windows/Linux). Thank you for your patience while we sorted out this issue.

8:31 PM PST

We are currently investigating an issue where profile information is failing to load for some users, resulting in blank profile pictures, display names and emojis.

We apologise for the disruption and please stay tuned for updates as we work to resolve this.
