Starting December 17, 2025, requests with request methods that aren't

## Security Security Starting _December 17, 2025_, requests with request methods that aren't compliant with [RFC 9110, Section 5.6.2](https://datatracker.ietf.org/doc/html/rfc9110#section-5.6.2) will be rejected by a first-layer Google Front End (GFE) before reaching your load balancer or its backends. Previously, such non-compliant requests would have been rejected by the load balancer or its backends with a variety of error codes. With the GFE now handling such requests, you might observe a small decrease in error rates. This change applies only to global external Application Load Balancers and classic Application Load Balancers.
