   Status: Resolved This incident was resolved. Rollbar processing pipeline latency (measured at p99) was elevated above our 30-second p99 SLO today during the following windows: 02:02AM - 02:35AM PDT: 30s - 7.0 minutes latency 06:02AM - 07:03AM PDT: 30s - 3.9 minutes latency 08:00AM - 09:02AM PDT: 30s - 37.2 minutes latency 09:02AM - 09:52AM PDT: 30s - 23.1 minutes latency p50 stayed at SLO (~5s) during the entire time period, and no data was lost. The initial cause analysis is a particular traffic pattern. We're investigating the root cause to ensure the system is resilient to this traffic pattern going forward.
