Description

The mwdebug cluster managed by the ServiceOps team have inconsistent AAAA DNS records for the primary IPv6 of the hosts. Some hosts have the AAAA record in the DNS for their primary IPv6 address, some don't.
See https://wikitech.wikimedia.org/wiki/DNS/Netbox#Mixed_clusters for more details about the possible risks of the current setup and the two alternative actions to move forward.

This is the list of the affected clusters and related hosts as of 2024-11-19:

  • have the AAAA record: mwdebug[1001-1002].eqiad.wmnet
  • lack the AAAA record: mwdebug[2001-2002].codfw.wmnet

The cluster is slated to eventually be decommissioned and sooner rather than later. I think we can just decline this. Any objections?

None apparently, doing so. But feel free to reopen
