And clicking https://about.gitlab.com/handbook/customer-success/account-management/ results in a 403 forbidden (because index.html is no longer since c4849035).

There's also a redirect at https://gitlab.com/gitlab-com/www-gitlab-com/blob/master/data/redirects.yml#L413-414 that will need to be looked at:

- sources: /handbook/account-management
  target: /handbook/customer-success/account-management/
