Had an idea to develop a tool to parse openstack release pages to see what's new from the CLI.
Continued maintenance after making sure cold migrations do work on running VMs and make sure they are started again after migrating.
Messaging timeouts occurred during maintenance. Found some settings to tune the neutron and nova oslo messaging library.

Learned about the HAProxy ansible module:
https://docs.ansible.com/ansible/latest/collections/community/general/haproxy_module.html
We decided to add ansible playbooks for enabling and disabling services. So we can disable the neutron controller in haproxy before restarting it. This prevents an issue where it is being flooded with requests while starting up and causing it to process SSL requests before even having loaded the SSL certificates.
Forgot that I had to visit the mortgage advisor at the end of the afternoon.
