Internal-facing infrastructure announcements

For significant internal facing infrastructure changes or updates, the Infrastructure Team can announce that change in the infrastructure announcement Zulip channel #t-infra/announcements. Please keep in mind that we would like to keep that channel to be low traffic and have a high signal-to-noise ratio.

By internal facing, we mean infrastructure that primarily is used by or only impacts project team members and other specific project-internal users (such as Dev Desktop users).
