context
We're in the process of transferring https://gitlab.com/gitlab-com/gitlab-docs under the gitlab-org
group and we need to change the DNS.
This should be done in step 1 https://gitlab.com/gitlab-com/gitlab-docs/issues/310#immediately-after-migration
rollout:
-
login to AWS prod console, go to route-53, change TTL of docs.gitlab.com dns entry to 1m -
change entry to:
docs.gitlab.com CNAME gitlab-org.gitlab.io.

after confirming it works as expected, increase TTL to 5m
rollback:
-
revert in route 53 to:
docs.gitlab.com A 35.185.44.232
-
revert TTL to 5m
