“Calm bedside manner. Decent load time.”

Pica's take. Mayo Clinic's site is calm and trustworthy, with sensible locks and a modest guest list. It loads in reasonable time and does not try to scare you. That alone puts it ahead of most health sites.

How we grade. Four checks, weighted equally: speed timed by our own browser, a security look from the outside, public reputation signals, and the network the site lives on. A look from the outside is not a server audit.
