Scaling Releases: Inside Meta's WWW Release Operations
summary
Meta runs continuous www releases with 10 releases per day, an average 4–5 hour change release time, and automation handling 95% of releases without operator intervention. The repo “dub dub dub” grows 10× changes and 5× tests since 2017, so tooling like Flightdeck and Gatekeeper orchestrate staged C1→C2→C3 deploys, autosignal-driven reverts, targeted stack reverts, tenant pipelines for product-specific releases, and metrics-driven investments to cut recovery time and operational load.
