I don’t know where else to report this, but
https://developer.atlassian.com/bitbucket/server/docs/latest/
Open source Bitbucket Server plugins links to Bitbucket | Git solution for teams using Jira which now redirects to https://bitbucket.org - not so useful…
I’m guessing it would be better for it to link to Log in with Atlassian account (since that’s the only url nowadays publicly accessible for the atlassian projects. ).
