Group policy cleanup and consolidation (9/5/2018 11:33:00 PM)
Starting now, and running through at least December, we will be deleting unused Group Policies, and merging and cleaning up existing group policies. This work is in preparation for upcoming Active Directory changes, and will be necessary to streamline the migrations that will be involved.
No significant changes are expected, but due to the nature of group policy editing, there is a small risk of error while editing and combining group policies.
Group policies which are not linked to any AD container will be deleted. There are a significant number of these discarded, and sometimes un-configured group policies, which we will delete to reduce the amount of work involved in the migration process.
Change in Windows Update location for campus workstations (9/21/2018 5:00:00 PM)
In September, campus workstations will be configured to download Windows Update files from an on-campus server. Currently workstations get update approvals from on-campus, but download the actual update files from Microsoft. This change will have all downloads pull from the campus data center instead. This will also be a stress test for the campus data center, to ensure we have the proper bandwidth available on the switches and firewalls.
Since the major update cycle occurs on patch Tuesday, and is released to the campus about 1.5 weeks after release from Microsoft, this means we will see an effective change of patch downloads on September 21st. Changes will be made ahead of time for the approval list, but the actual large patch load will occur when the September updates are released to the full campus.
Servers already pull update files from a server in the data center, and will not be affected by this change. No outage is expected with this change, but network utilization will be monitored during the first update cycle.

Cherry Hall network upgrade (9/24/2018 6:00:00 AM)
We will be replacing the access switches at Cherry Hall. This will result in a loss of phone and network for individual floors during this period.
Toy Museum network upgrade (9/25/2018 6:30:00 AM)
We will be replacing the building switch at TMM. This will result in a loss of phone and network during this period.
Campus firewall firmware upgrades (9/29/2018 10:00:00 PM)
The campus edge and data center firewalls will receive a firmware upgrade. At this time we will tentatively look at the new 8.1 software train for the campus firewalls.
The campus network edge firewall upgrades should not cause an outage.
The campus data center firewall upgrades will likely cause up to 4 outages of 1 minute each, as the firewalls are upgraded, and the active routing path changed. We have had outages as short as 30 seconds, but this is our first upgrade cycle since upgrading the data center switches, so longer outages may be possible.
Firewall network path balancing change (10/13/2018 10:00:00 PM)
A change will be made to the campus Edge and Data Center firewalls, to allow better path balancing. There will be a few brief network outages for Internet traffic and for server traffic while the changes are made.
