Hi,

Like we mentioned in the timeline [0], we are starting the work to redirect the old host names to the new ones [1].

We will share more details in the next few days when we actually deploy the DNS change. This is a heads up before the change actually happens in case you haven't tested your code with the new cluster, last warning.
