Unresolved incident: Errors and latency for pipelines.

Nov 12, 2026

Nov 11, 2026

Increased error rates on Agent API
Resolved - Increased latencies and error rates with the Agent API have subsided. This performance regression affected a specific subset of our customers with tenancy on one of our database clusters.
Nov 11, 20:15 UTC
Monitoring - With remediations applied, we are beginning to see recovery. We're continuing to monitor the decreasing latencies and error rates for the Agent API as services stabilize.
Nov 11, 20:07 UTC
Identified - Our on-call engineers have identified a performance regression causing API issues for a subset of our customers and are applying remediations.
Nov 11, 19:38 UTC
Investigating - We're investigating elevated errors and latencies with the Agent API.

Increased latency and error rates
Resolved - We have seen recovery and latency has returned to normal.
Nov 3, 20:22 UTC
Monitoring - We’ve scaled out the resources that process incoming webhooks and are seeing recovery. We’re now working through the backlog of queued jobs and continuing to monitor
Nov 3, 19:43 UTC
Update - We are continuing to investigate. At this time, the issue is limited to a small subset of customers.
Nov 3, 18:54 UTC
Investigating - We're seeing increased latency and error rates for a subset of our customers. We're currently investigating and will provide status updates as they become available.
Nov 3, 18:14 UTC
Elevated API error rates
Resolved - API errors have subsided and we're seeing recovery. From 19:19-19:39 UTC we saw elevated errors on the Agent API and REST API.
Nov 3, 20:12 UTC
Identified - We're seeing recovery with previously elevated API error rates.
Nov 3, 19:59 UTC
Update - We are continuing to investigate this issue.
Nov 3, 19:42 UTC
