Some things added on this branch: - icons and client logos at known paths - some spam redirects - some redirects for docs/latest/foo /docs/foo - redirects for the two ‘moved’ pages (k8s and envoy intros) I am going to be monitoring the traffic this week on Netlify to make sure we have a good coverage with redirects where needed. We also now prompt users to file issues directly from the 404 pages which should help flag things we miss too.
