Upgrade email notification template

Upgrade email notification template

The purpose of this template is to provide an easy way to copy and paste, to create an upgrade notification email which can be shared on our mailing lists such as the ci-users@centos.org list, when we are rolling updates out to the CentOS CI OCP4 cluster.

Subject: Scheduled <MAINTENANCE/UPGRADE> Notification: CentOS CI <STAGING/PROD> Openshift Cluster 


Dear CentOS CI User,

The upgrade is not expected to be service affecting, however there might be periods of slight performance degradation during this maintenance period. We apologise for any inconvenience that this may cause.


Kind regards,
