“Go Dark” is a general-purpose, SEO-friendly utility that allows you to easily take your website offline (blackout) in protest of political issues, climate advocacy, net neutrality, censorship opposition, or other custom causes.
When your website is “dark”, it returns a 503 Service Temporarily Unavailable HTTP status code. This informs search engines that the offline state is temporary, preserving your SEO rankings, and provides browsers with a Retry-After header.
