Episode notes
Stage Launch, Lunch, Then Metrics Surprise
- Gerhard describes launching Pipely on stage in Denver and then checking metrics after lunch when things started failing.
- He under‑provisioned instances, traffic spiked, CPU hit 100% and the new CDN began to fail under load.
Always Use Blue‑Green Deploys
- Always introduce changes alongside the existing system so you can revert quickly if something breaks.
- Use blue-green deployments to run new and old infrastructure in parallel and rollback by redirecting traffic.
Hike While Rollback Saved The Day
- While Pipely was overwhelmed, the hosts went hiking and avoided a production firefight because they had blue-green fallback.
- The issue was fixed by restoring previous DNS records, routing traffic back to the old CDN within minutes.
