Update timeline
- investigating Sep 01, 2026, 05:00 PM UTC
We're investigating slowness when pausing, resuming, or saving checks. Some of these actions may take several seconds to complete. Monitoring itself is unaffected - checks are still running and alerting normally.
- identified Sep 02, 2026, 02:30 PM UTC
We've identified the cause as elevated load on the internal system that synchronizes check state. This is causing delays of up to 5 seconds when pausing, resuming, or saving a check. The requested changes are still being applied correctly, just with a delay. No monitoring, alerting, or data collection has been impacted.
- monitoring Sep 02, 2026, 02:32 PM UTC
This incident should be resolved. We are monitoring our system. Between 5PM and 9 PM UTC, pausing, resuming, and saving checks intermittently took up to 5 seconds to complete due to elevated load on our internal service. All changes submitted during this period were applied successfully, and monitoring and alerting were unaffected throughout. We've since reduced load on the affected system and are making changes to prevent a recurrence.
- resolved Sep 03, 2026, 09:38 AM UTC
The system has stabilized.
