   On 09:43 UTC, QStash experienced degraded service when a high number of requests to a specific domain were throttled, resulting in timeouts during an unexpected phase of the TCP connection establishment. These requests and resulting retries triggered excessive consumption of network resources and negatively impacted all users. We have added more resources to QStash as a quick remediation and as for the resolution, we have improved the timeout mechanism to detect and fail-faster in such cases.
