Hi,

today 2023-09-11 we will be conducting some internal Cloud VPS DNS service operations:

* change the DNS recursor of every virtual machine running Cloud VPS from 208.80.154.143 and 208.80.154.24 to 172.20.255.1 (this is traditionally done via /etc/resolv.conf) * change the real server behind the authorizative DNS ns1.openstack.eqiad1.wikimediacloud.org, including the IP address, from 208.80.154.11 to 185.15.56.163

This may affect briefly some virtual machines, but the new DNS servers have been running for a while already and we are not anticipating a major impact (famous last words?).

Please report any problems you may find.

Some phabricator tickets tracking this work are: * https://phabricator.wikimedia.org/T345240 cloudservices1006: put into service * https://phabricator.wikimedia.org/T346033 cloudservices1004: decomission * https://phabricator.wikimedia.org/T342621 eqiad1: cloudlb: transition DNS clients (VMs) to the new BGP-based recursor VIP

regards.
