IT has a variety of defined maintenance windows and scheduled for different components of our computing environment. Some maintenance work is announced and scheduled explicitly. Others are scheduled on a recurrent basis. Different categories of updates/windows are included below for reference.
Applications
Applications are generally deployed during either the daily applications deployment window of 5pm-7pm, or occasionally during the systems infrastructure change window Thursday evening from 10pm-2am.
Windows Server Patching
Windows server patching is performed on the 2nd (development/test servers) and 3rd (production) weeks of the month on thursday evening from 10pm-2am.
Linux Server Patching (Infrastructure Team Servers)
Linux server patching is performed on a continuous basis (unattended upgrades are set to run on demand), but there is also a set/explicit patching/update window performed on the 2nd and 3rd wednesdays of the month at 3am. For certain updates when manual intervention is required, they will be scheduled either during the applications windows every evening or during the thursday night window.
