2020 ERIS Systems Maintenance Schedule

To ensure premium supportability, security and performance, ERIS strives to keep all systems up to their most current and/or stable revisions. To minimize disruption, ERIS will complete all non-critical production changes such as patching, firmware updates, etc. on the last Saturday of every month from 7AM to 7PM. 
The exact schedule is outlined below. There have been a few adjustments for holidays and to avoid conflict with the Monthly Information Systems Maintenance (ISM) window. 
ERIS also patches non-production DIPR Hosted Virtual Servers (VMs) ahead of the schedule outlined below. Typically this falls on the third Wednesday of each month starting at 10a.m. Please see ERIS DIPR Hosted Virtual Servers (VMs) - Monthly OS Patching Schedule for details.

Monthly Information Systems Maintenance (ISM) is scheduled separately from ERIS System Maintenance and is performed by the IS Operations teams. This routine maintenance reduces the risk of unscheduled outages on our computer network and to the Internet. The ISM window is typically scheduled for the early hours of the third Monday of each month.
