This Sunday morning we have a number of maintenance activities planned.

• Between 6 am and 10 am Digital Collections at Middlebury / CONTENTdm (middarchive.middlebury.edu) will be off-line in order to upgrade to version 6.6.
• Between 7 am and 8 am there may be a less than 5 minute interruption of DNS and DHCP services as the underlying systems for these services are upgraded.  As these services are part of a high availability configuration, we expect a minimal if any impact to end users.
• Between 7 am 10 am we will be testing the failover of high availability components of our network that include building aggregation switches and redundant uplinks for the below buildings, no service impact is expected:
  •     Service Building
  •     Axinn
  •     Public Safety
  • Between 8 am and 10 am we will be evaluating some Internet routing options that may result in isolated, intermittent Internet sites being reachable, we expect this impact to be short lived and not wide spread.
• Between 8 am 10 am we will be running some network/server security tests that we do not expect to have a noticeable impact.

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