  2. 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.

  3. 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.
