Sunday morning maintenance

Categories: Midd Blogosphere

This Sunday morning between 7 and 10 am we will be performing some fine-tuning of our Internet gateway routers and firewalls that will include some Internet routing prioritization and optimization as well as some firewall configuration changes.  We do not expect any noticeable interruptions of services but are performing this during our maintenance window as a precaution.

Between 7 and 9 am we will be upgrading our Internet firewalls.  While the Internet firewalls are a pair with failover, there can be an up to 30 second interruption of service as each failover takes place.  We are expecting 3 less than 30 second Internet service interruptions during this period.

Between 8 and 10 am we will be re-routing connectivity to a specialized video conferencing network segment, the video conferencing service will be off-line during much of this window.

Between 8 and 9:30 am we will be upgrading Web Help Desk, there will be a less than 10 minute service interruption during this period.

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.

LIS is planning the following maintenance activities next weekend, on Saturday December 21st and Sunday December 22nd:

  • On Saturday, December 21st between 7 am and 12 pm (noon),  we will be performing maintenance on our servers. For many services, there may be up to a 15 minute interruption. Middlebury and Monterey’s email and primary web sites will not be affected by this maintenance work.
  • On Sunday, December 22nd between 7 am and 10 am,  we will be conducting a test of the redundancy of our network. Some campus buildings will not have network access for approximately 30 minutes during this test.  A list of these buildings is available at the end of this message.
  • On Sunday, December 22nd between 8 am and 12 pm (noon),  we will also be upgrading our Internet firewalls.  We expect several interruptions of Internet connectivity lasting approximately 30 minutes during this period.  We will continue to test and fine-tune the new firewall into the afternoon on Sunday. While we do not expect significant service interruptions in the afternoon, it may be necessary to make adjustments that could cause brief interruptions for isolated services. (You can see the availability of our major systems at http://www.middlebury.edu/offices/technology/help/alerts).
