= TL;DR - The codfw deployment server is now Naos: naos.codfw.wmnet [1]. Its SSH fingerprints are available at [2]. - Mira is no longer a deployment server. - Naos is also the current active deployment server until May 3rd [3], [4]. - As always, please use the DNS record deployment.eqiad.wmnet to know which deployment server is the active one.
= Detailed version: Few days before the datacenter switchover to codfw performed last week [3], [4], with perfect timing, the existing codfw deployment server Mira manifested hardware issues. Being Mira an old server, also out of warranty, a new deployment server in the codfw datacenter was deployed and configured.
As a result, from now on, the deployment server for the codfw datacenter is Naos: naos.codfw.wmnet [1]. You can find its SSH fingerprints in [2].
As part of the datacenter switchover procedures [4], also the deployment server was switched to codfw, hence Naos is currently the active deployment server, until the switchback to eqiad as master datacenter, scheduled on May 3rd [3], [4]. The DNS entries for both deployment.eqiad.wmnet and deployment.codfw.wmnet always point to the active deployment server and should be used to verify which one is the active one.
As always, a large message of the day (MOTD) is shown to alert people to not use the passive deployment server on login, and it is now shown on both Tin and Mira.
I've also updated all the references to Mira that I've found on Wikitech, but please verify if you have any direct reference to it that might need to be updated.
Thanks, Riccardo
