This URL redirects to https://www.acn.gov.it/portale/home.

The site’s front door pointing at the page it serves there — a locale or CMS landing path, not a move. The origin is still the address of the site, so history stays under it rather than forking to a path that depends on where the measurement ran. Lighthouse follows the redirect, so the numbers below describe the page actually served; the only cost is an extra hop on each run.

Lab data is measured using Lighthouse, Mobile mode unless otherwise specified. Field data is reported from Chrome UX Report (using p75 measurements).
