dashboards.gitlab.com is no longer publicly accessible?

There are various references across the internet about being able to access https://dashboards.gitlab.com/

One last thing: our Grafana dashboards are open, so if you're interested in digging into our metrics in more detail, visit dashboards.gitlab.com and explore!

Other references:

But when I try to visit https://dashboards.gitlab.com/ now, it just gives a DNS name not resolved error.

Did this change with the GitLab IPO on 2021-10-14? Why are the dashboards no longer public?
