Issue Summary:
On August 28, 2024, from 11:13 AM PDT to 11:22 AM PDT, a small percentage of users in the Europe and Asia-Pacific region encountered issues with various actions including connecting to Slack, loading conversations, and sending messages.

We detected a spike in error rates which we traced back to an upstream provider conducting unplanned maintenance on a service many core Slack functions rely on.

To mitigate user impact, we temporarily diverted traffic from the affected databases. Once the error rates returned to normal and the upstream provider restored functionality, traffic was reverted back to the normal databases.

We apologize for any disruption to your work day.
