We are currently investigating an issue causing message delivery delays of up to five minutes across all supported platforms. This may affect users sending or receiving messages between Google Chat, Microsoft Teams, and Slack. At this time, the underlying cause has not yet been identified, and we do not have an estimated time for recovery. Our engineering team is treating this as a top priority and is actively analyzing system performance, queues, and external dependencies to isolate the source of the delays. We will provide an update as soon as more information becomes available.

We have implemented changes intended to improve system performance and reduce message delivery delays. Early results are positive, and overall latency has decreased since these updates were applied. At this time, we are closely monitoring the system to confirm stability before marking the incident as resolved. We will provide another update once we have sustained healthy performance across all affected services.
- resolved Nov 19, 2025, 02:54 PM UTC
System performance has returned to normal, and message delivery is now operating as expected across all platforms. Our team has been monitoring the environment and has confirmed stable performance following recent adjustments. This incident is now resolved. Thank you for your patience while we worked to restore normal service.
