WHAT ARE WE DOING?
There is a planned downtime scheduled for Wednesday, Feb. 20 that includes all the interactive systems (*gpvm* and miscellaneous others), dCache pool nodes, worker nodes and related servers, CMS systems and other scientific servers.
• Per a recommendation from Networking, Computing will be pushing out an update to all systems, removing secondary DNS entries from the DNS nameserver search path, and configuring them to exclusively use the Anycast DNS. This should have no noticeable impact.
• There will be a standard monthly patch to Jenkins.
• A small number of kernel updates will be done. Impacted customers will be contacted directly.
WHEN WILL THIS OCCUR?
Wednesday, Feb. 20; between 8 a.m. and noon Central Time
WHAT IS THE IMPACT TO YOU?
There should be no impact except to the systems receiving kernel updates as those will have to be rebooted. Impacted customers will be contacted separately with details.
WHAT DO YOU NEED TO DO?
Be aware that these activities are taking place. Open a Service Desk ticket if you notice any issues after the maintenance window.
