Elastic build machines now use Turborepo cache hits to prevent downgrades
↗
Vercel's elastic build machines now account for Turborepo cache hits when deciding whether to shrink to a smaller machine, so warm-cache builds no longer trigger downgrades that could starve subsequent cold-cache builds.
Previously, a warm-cache build's lower CPU and memory usage could cause the elastic system to downgrade the machine, leaving a later cold-cache build without enough resources to finish. The fix is automatic for all builds using elastic build machines and requires no configuration change.

Elastic build machines now consider Turborepo cache hits when deciding whether to use a smaller build machine.
A warm-cache build uses less CPU and memory than a cold-cache build, and downgrading based on that lower usage could cause a later cold-cache build to fail.
The change applies automatically to all builds using elastic build machines with no action required.
