The Vercel Observability dashboard now includes a dedicated view for middleware, showing invocation counts and performance metrics.

Observability Plus users get additional insights and tooling:

• Analyze invocations by request path, matched against your middleware config

• Break down middleware actions by type (e.g., redirect, rewrite)

• View rewrite targets and frequency

• Query middleware invocations using the query builder

We’ve optimized connection pooling in our CDN to reduce latency when connecting to external backends, regardless of traffic volume.

• Lower latency: Improved connection reuse and TLS session resumption reduce response times by up to 60% in some regions, with a 15–30% average improvement.

• Reduced origin load: 97% connection reuse and more efficient TLS resumption significantly cut the number of new handshakes required.

This is now live across all Vercel deployments at no additional cost.

Rate limiting now has higher included usage and broader availability to help protect your applications from abuse and manage traffic effectively.

The first 1,000,000 allowed rate limit requests per month are now included. Hobby teams also get 1 free rate limit rule per project, up to the same included allotment.

These changes are now effective and have been automatically applied to your account.
