Will there be an impact on the Platform apps?

During the Sunday change, the Image Registry will be read-only for up to 15 minutes.

On Monday morning the API and web console will be updated and may be briefly disrupted.

This maintenance will involve draining and rebooting nodes to update the Openshift version as well as the firmware. It will be disruptive, so please monitor your applications.

Do I need to do anything?

No action required other than the usual monitoring of your applications.

The new web console combines the Admin and Developer perspectives and updates the UI styling.
