Point app links at app.dnsimple.com

[weppos]

Summary

The application moved from dnsimple.com to app.dnsimple.com, so every support link that points at a page behind login now uses the app host. The /user and /dashboard links returned a 404 on the bare host, and the /login and /signup redirects drop the query string, which cost the header CTA its UTM parameters. Sandbox moved the same way: sandbox.dnsimple.com now serves the marketing copy, and the web interface is at app.sandbox.dnsimple.com.

The Entra redirect URIs stay on dnsimple.com. DNSimple sends the bare host as the redirect URI in the authorization request, and docs/subapps.md records that host as a durable compatibility boundary, so a registration on the app host fails at Entra. dnsimple/dnsimple-app#36593 changes that decision, and this article needs a follow-up when it lands.

Files changed

• content/articles/ — the user, dashboard, login, signup, email verification, and Sandbox links use the app host
• layouts/default.html — the header CTA uses the app host, so the UTM parameters survive
• CONTRIBUTING.md, .cursor/rules/article-structure.mdc — the link conventions record the app host

The marketing links stay on dnsimple.com. I checked each one against the site route set and confirmed that it serves on the bare host.
