Users may still be experiencing issues loading Slack, using workflows, sending messages or loading threads. API-related actions may also be degraded in speed. While some users may notice improvements, we remain focussed on resolving the issues and are working on this with the highest urgency.

Remediation work involves repairing affected database shards, which are causing feature degradation issues. This has become a diligent process to ensure we're prioritizing the database replicas with the most impact. 

We are working to restore functionality to all of the database shards, and will continue to share updates here as we have more.
