System and Network Maintenance this Sunday

Categories: Midd Blogosphere

During our regular maintenance window this Sunday, Oct 19th between 6 and 10 am we have the following activities planned.

 

  • A patch will be applied to the DNS servers requiring sequential reboots. DNS resolution may see some slow responses for up to 20 minutes
  • Two of our spam filters will be moved between racks in one data center. There’s sufficient redundancy that no impact will be seen
  • One of our database servers and a print server will be rebooted. Printing queues may be unreachable for up to 15 minutes
  • One of our two ISP circuits will be down for 2 hours while the provider performs maintenance

              o   We have sufficient redundant bandwidth. Internet reachability will not be impacted

              o   Point-to-Point VPNs may drop a few packets, twice, during route changes

  • The VSphere interface to our virtualized server environment will be patched and rebooted. Reachability will be down for up to 15 minutes
  • Middfiles will be rebooted and unreachable for up to 15 minutes

 

We appreciate your patience as we continuously strive to keep our systems functioning optimally.

System and Network Maintenance this Sunday

Categories: Midd Blogosphere

During our regular maintenance window this Sunday, Oct 5th between 6 and 10 am we have the following activities planned:

  • Middfiles will be offline for up to 2 hours within the 6-10 maintenance window while the storage arrays are moved from the Library data center to our new data center.

o   All files on Middfiles will be unavailable during this window, including home directories, Orgs, Classes, etc…

 

  • The SAN storage controllers will receive a small point release upgrade. No downtime is associated with this work.

 

  • We will move a pair of fiber channel switches form the Library data center to our new data center. Hosts served by these switches are dual connected and may see a brief (~5 seconds) unavailability.

 

  • The border firewalls will receive an upgrade. There are 4 brief Internet outages expected during the upgrade, each lasting up to 30 seconds.

o   All of Middlebury Internet access and the VPN to MIIS will be impacted.

 

  • One of our two Internet Service Providers will be performing a hardware change. This will result in one of our Internet circuits being down around 7am for up to 30 minutes. We have adequate Internet bandwidth on either single circuit to handle our needs during this time.

o   Point to point VPNs may see a brief drop while the path re-routes.

  • The Filemaker Pro database service will be interrupted for about 10 minutes between 8 and 9 am for application maintenance.

 

We appreciate your patience as we continuously strive to keep our systems functioning optimally.

Security Note – ‘Shellshock’ Vulnerability

Categories: Midd Blogosphere

As you may have read in mainstream news media outlets, a vulnerability was recently discovered in the Bourne Again Shell component of the Linux operating system. This vulnerability could allow an attacker to execute shell commands through the shell environmental variables. It has also been leveraged for denial of service attacks and other malicious activity.

ITS has already patched relevant local systems and is expecting vendors to patch any relevant externally-hosted systems. There is no evidence to suggest that Middlebury assets have been compromised.

More information about the vulnerability is available on the ITS Information Security web site’s ‘Threat Bulletin’ area: http://www.middlebury.edu/media/view/486102/original/middlebury_threat_bulletin_shellshock.pdf

If you have specific questions, please feel free to email infosec@middlebury.edu.
