IT system and network maintenance this Sunday (12/15/2013) and next weekend (12/21/2013, 12/22/2013)

Categories: Midd Blogosphere

LIS is planning the following maintenance activities this Sunday, December 15th between 7 am and 10 am:

  • We will be upgrading our VPN system (vpn.middlebury.edu). There will be a less than 30 minute service interruption of VPN access to the College from off-campus between 7 am and 9 am.
  • We will be upgrading the firewall at the Monterey Institution of International Studies. There will be a less than 30 minute service interruption of Internet connectivity to MIIS. This will include the site-to-site VPN connection between MIIS and Middlebury.
  • We will be applying a patch to our MiddCloud system that includes MiddFiles.  There will be a less than 15 minute service interruption to MiddFiles between 7 am and 8 am.

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).

As always, we appreciate your patience and understanding as this essential maintenance work is completed in our continual effort to improve our IT services.

(1)    Between 6:30 and 10:00 am EST we will apply a service pack to our Exchange cluster that provides email services for @middlebury.edu and @miis.edu.  Due to the redundant configuration of our Exchange environment we do not expect there will be a service disruption.  You may be asked to re-authenticate during or following this window the next time you connect with an outlook.

Additionally there will be an approximately 10 minute interruption of Web Print services generally and approximately 30 minute interruption of printing services generally when the papercut database is upgraded.  Additionally a number of printing stations (generally Kyocera-Mita) will require a hands-on visit, a software update with a restart that will take place during the later hour of our maintenance window.

We appreciate your patience as these essential maintenance activities are performed.

Emergency Maintenance Window for Middfiles

Categories: Midd Blogosphere

We appreciate your patience and our apologies for scheduling this maintenance on short notice and outside our regular maintenance window of Sunday mornings.

Sunday morning Maintenance

This Sunday morning between 7 and 8:30 am we will be upgrade MiddFiles, there will be a less than 15 minute interruption of all connectivity to MiddFiles during this window.  We have been continuing to work intensively with our vendor to isolate intermittent disconnects of all client computers to MiddFiles that are occurring due to unexpected and abnormal termination (core dump) of the smb service.  When the smb service crashes, all of the client lose their connection to middfiles and need to reconnect, while this process doesn’t take long, it is noticeable and frustrating and particularly so if it is happening often, this is especially the case for database applications that are most sensitive to loss of their access to their underling storage environment.  We have been making steady progress working with our vendor to apply patches and tune settings in order to reduce the frequency of these service interruptions, from as many as 40 a day a couple of weeks ago to 15 a day earlier this week to 6 yesterday.  While we’re not out of the woods yet, we do believe that we are getting closer to putting this issue behind us.

Please don’t hesitate to contact me with any questions or updates, in particular if we haven’t already touched base related to the impact this is having in your work groups area.
