Upstash incident
QStash - Message delays for Flow Control configurations
Resolved on December 1, 2025.
We identified and fixed a bug that could cause messages with Flow Control enabled to be delayed longer than their configured delay, resulting in unexpectedly long pending times. The fix is in place and the issue should not recur. If you’re still seeing unusually long-delayed messages, please contact [email protected] and we can help with remediation.
