Systems and Network maintenance this Sunday morning

Categories: Midd Blogosphere

During our maintenance window this Sunday morning between 6 and 10 am we have the following actives planned:

We will be upgrading the Middlebury and Bread Loaf campus wireless network.  This will result in each wireless access point on both of these campuses rebooting, as a result we expect a less than 10 minute interruption of wireless services throughout both campuses, likely between 6:30 and 8:00 am.

We will upgrading the our VPN (virtual private network) appliance that provides service to the JunOs Pulse VPN client.  Between 6:30 and 8:00 am there will be a less than 30 minute service interruption of off-campus VPN access to Middlebury’s network.

We will be upgrading our MiddCloud file serving environment that includes MiddFiles and other network file shares generally used by the Science departments.  Between 7:00 and 8:00 am we expect a less than 10 minute service interruption of MiddCloud.

We appreciate your patience as we strive to keep our systems and network operating optimally.
