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:
*

*

clients (VMs) to the new BGP-based recursor VIP
regards.
