Upload a directory and it is served worldwide, with a certificate, caching and the same rules Shield applies to everything else.

A Pages site is served only on a hostname you own. There is no subdomain of ours to publish on, and that is a decision rather than a missing feature: user content under our own name would put the console, the identity provider, the status page and every device using our public resolver behind a single browser blocklist entry. Your domain carries your reputation, which is the right place for it.

Each upload is a deploy, and a deploy never changes once it is finished. Going back to an earlier one is instant: nothing is copied and nothing is rebuilt, because the deploy is part of where its files are stored — only a pointer moves. The edge is told to drop its cache at the same moment, so a rollback is visible immediately rather than when the last cached file happens to expire.

Ordinary static-site behaviour, stated rather than guessed at: /docs is docs.html when that exists and docs/index.html otherwise; a directory asked for without its trailing slash is redirected rather than served, so relative links resolve where their author meant; a missing page gets your 404.html with a 404 status, not a 200. A _redirects file gives exact and wildcard rules, and _headers lets you set your own response headers — though not ones that would rewrite what the edge decided.
