  1. investigating Aug 20, 2025, 02:59 PM UTC

    From 2025-08-20 07:25 PST, we experienced issues with our query capabilities for some customers and users may see their charts/dashboards slow to load or unavailable. Our team is investigation, no action is needed from customers at this time. We will post updates as we recover the systems.

  2. investigating Aug 20, 2025, 03:25 PM UTC

    We are still investigating, still not clear on the root cause. Trying some ways to mitigate.

  3. monitoring Aug 20, 2025, 03:39 PM UTC

    System is back to normal from 8:27am after mitigation, still investigating the root cause

  4. resolved Aug 20, 2025, 04:07 PM UTC

    We have some theory on the root cause, will work on them ASAP and run an internal post-mortem afterwards
