After the release of jaas.ai (btw, check out the new visual design, inline with the new ‘Suru’ branding and Vanilla 2.0), the Web-team worked on migrating the documentation from docs.jujucharms.com to the new jaas.ai/docs.
The new Juju docs page is now aligned to the other docs sections across Canonical products, and moved to the main website navigation without using a separate subdomain url.
Hi @szeestraten thank you for your feedback, I opened issues based on your points.
About Discourse I replied in that discussion, while the SEO situation should improve after a few days once Google indexes the new docs urls.
