We are seeing the job dispatch times are back to normal.
Buildkite·Increased latency and error rates
We identified that the majority of the impact was for a single customer and was caused by a database failover. We are investigating the cause and we will work with the impacted customer.
Buildkite·Elevated error rates
Between 23:16 and 23:27 we saw elevated error rates across our platform due to a scheduled database upgrade. That upgrade was not intended to cause any impact, but due to an unforeseen dependency on this database customers experienced error rates averages 2.5% during this period.
Buildkite·Delays with Hosted Agents jobs
Processing of Hosted Agents jobs are no longer delayed.
Buildkite·Buildkite response to the eMudhra certificate compromise
All services that power Buildkite have been updated to distrust the affected certificates, and updated releases are available for the components we distribute that run in customer infrastructure: Buildkite agent: v4.7.0 and v3.138.2 Buildkite CLI: v3.64.2 bktec: v3.3.1 elastic-ci-stack-for-aws: v7.8.0 agent-stack-k8s: v0.52.0 We recommend updating to these versions to prevent exposure to the affected certificate providers.
Follow Buildkite
Your coding agent knows when Buildkite is down, and tells you when a failure is theirs, not yours. You can also get Buildkite incidents in a feed reader or in Slack.
Install the outages.live MCP server, so that when something breaks you can tell if the cause is a provider we depend on and not my code. It reads the official status pages of cloud, AI, payment and developer providers and gives you their incidents as MCP tools.
Add it as a remote MCP server named "outages" at https://outages.cc/mcp (Streamable HTTP, no authentication), with your CLI command or your MCP config file.
Then:
1. Make sure it connects and shows the tools get_provider, list_feed and send_feedback.
2. Call get_provider with "buildkite" and tell me if Buildkite has a problem right now.
3. From now on, when a call to a third-party service fails or becomes slow, call get_provider for that service before you change my code.Paste this into any coding agent. It adds the server with its own MCP setup.
