Legacy observation Operational Degraded Partial Outage Major Outage Maintenance No Data
We continue to observe degraded checkout performance. Our engineering teams are working on establishing an alternative network transit path to alleviate networking performance issues.
investigating
We've received reports of degraded checkout performance with GitHub repositories when using Hosted Agents and are investigating.
The mitigation is rolling out and we are seeing recovery. We will continue to monitor and provide an update.
identified
Since 2026-09-30 20:52:36 UTC on 30 September, small amount of incoming GitHub webhook deliveries to Buildkite pipelines are being rejected, so the related builds are not created.
For people who use GitHub.com may affect ability to receive status checks. We have identified the cause and are deploying a mitigation. This does not affect GitHub Enterprise Server and other SCM providers.
We observed a slight increase in latency for build creation isolated to a few customers, this has now passed and we are seeing signs of improvement.
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.
We are seeing improvements across the affected services, and are seeing services return to normal functionality. We are continuing to monitor and are determining the root cause.
investigating
We are continuing to investigate elevated error rates across multiple services, and are working to determine the cause.
investigating
We are continuing to investigate this issue. We are seeing impact on the Agent API which will affect job scheduling, artifact uploads, and an increase in 5xx responses from the Agent API endpoints.
investigating
We've spotted that something has gone wrong. We're currently investigating the issue, and will provide an update soon.
We have deployed mitigations and have observed recovery across Hosted Agents. We will continue monitoring.
investigating
We're seeing increased latency and error rates within our Hosted Agents. We're currently investigating and will provide status updates as they become available.
We're seeing recovery in hosted job scheduling rates. Your jobs should run, but there may be some delays as we work through any backlogs.
investigating
Some job dispatches to hosted agents are timing out, leading to jobs starting late. We're currently investigating and will update again soon.

identified
We're beginning to see recovery with delayed job dispatch for Hosted Agents. We are currently working through the backlog of delayed jobs.
investigating
Our engineers are continuing to investigate an issue with delayed job dispatch for Hosted Agents. Job dispatch for self-hosted agents remains unaffected.
investigating
We're investigating an issue with job dispatch to our Hosted Agents.
We are seeing successful email deliveries and are monitoring processing of our outbound email queue.
identified
Our on-call engineers are working on failing over to an alternative upstream email provider to restore outbound email notifications. No other Buildkite services have been impacted by this disruption.
identified
We are experiencing delivery issues with email notifications due to an issue with an upstream provider.

Agent API
monitoring
Agent connectivity is recovered, but some agents are not reconnecting automatically after the earlier forced disconnects.
We recommend restarting agent service to make agents reconnect.
monitoring
At 06:04 UTC we deployed a defective request routing change to `agent-edge.buildkite.com`, which caused some customers' agents to abruptly disconnect.
At 06:09 UTC we noticed the problem, and immediately reverted the change. We began to observe recovery at 06:10 UTC, and are continuing to monitor.

Hosted Agents
monitoring
We have confirmed that all background workers have caught up as of 1:13am UTC. Hosted Agents dispatch has returned to normal.
We'll continue to to monitor the service and are checking remaining retries.
investigating
We’re investigating elevated latency in background worker processing between approximately 12:39am and 1:02am UTC.
Processing has since caught up and was near real time as of 1:13am UTC. We’re continuing to monitor the service and are checking remaining retries.
Some builds or hosted-agent-related operations may have experienced delays during this period. We’ll provide another update as soon as we have confirmed the service is stable and have more information about the cause. We apolo...
