 ====== Summer Maintenance Schedule ======
+==== Gitlab PostgresSQL Upgrade Maintenance Window====
+  * SYSTEM: Gitlab PostgreSQL Server
+  * DATE:  Tuesday, August 29, 2017
+  * START TIME:  0800
+  * DURATION:  2 hours
+(Please note this is an estimate;  systems may be up sooner or later
+than expected, due to unforeseeable circumstances.)
+**AFFECTS:**
+During this downtime window, the ICS Gitlab server will be unavailable.
+**REASON:**
+The PostgreSQL server used by the Gitlab server is being moved to another
+host where a newer version of PostgreSQL has been installed. We need
+about two hours to make the full conversion.
+<code>
+                  pgsql 9.5 -> pgsql 9.6
+</code>
+Please send any questions or concerns to helpdesk@ics.uci.edu.
+==== Mail Delivery Server Upgrade Maintenance Window====
+On Tuesday, 8/29, we will be deploying a new mail delivery agent.
+**Affects:  **
+During this maintenance window a new mail delivery server will replace the older mail delivery servers.  Email that is delivered locally may be delayed by up to an hour during the cut over.  No mail will be lost and this will will only affect email that is delivered locally.
+**Reason:**
+Upgrades are required in order to replace underlying CentOS6 and Puppet2 host infrastructure.
