The Slack thread said <code>ConnectTimeoutError</code> to an internal tracing endpoint. Four Lambda functions had been moved into a VPC the day before so they could reach <code>tracer.internal.ferkakta.net</code> — an internal ALB at <code>10.x.x.x</code>, only reachable from inside the VPC. The migration was verified, the API returned success, the ticket should not have existed.</p> <p>The people who built this system had moved on to other projects. The people using it were in a different timezone. There was no architecture doc, no runbook, no one to pair with. I had CloudWatch, a kubectl context, and AWS credentials.</p>
