Summary

https://pro.reactonrails.com is currently returning 500, while the live Pro docs landing page at https://reactonrails.com/docs/pro/ is healthy.

Observed on March 26, 2026 UTC:

• https://pro.reactonrails.com -> 500
• https://reactonrails.com/docs/pro/ -> 200
• https://reactonrails.com/docs/pro/react-on-rails-pro/ -> 404

Why this matters

There are still repo docs/code references and at least some live site content that point users at pro.reactonrails.com. That currently sends users to an error page instead of a working Pro landing page.

Suggested direction

• Restore or redirect pro.reactonrails.com to the intended canonical destination
• Audit the current site for any remaining links back to pro.reactonrails.com
• If /docs/pro/ is the canonical Pro docs landing page, make that explicit across site content and redirects

Non-duplicate note

This is distinct from issue #33, which tracks /docs/pro as the canonical landing page. This issue is about the dead pro.reactonrails.com destination itself.
