Systems Maintenance Sunday, Feb 8th

Categories: Midd Blogosphere

During our regular maintenance window this Sunday, February 8th  we have the following activities scheduled:

 

  • Starting at 5am EST the Middlebury website, http://www.middlebury.edu, will be put into a read-only mode for approximately 5 hours for an upgrade. After the upgrade completes the site will be put into full read/write mode.
    • What’s available during this read-only period?: All publicly-accessible content on our website will be available.  Links will continue to work.  Drupal webforms are hosted on another site and can be accessed and edited as normal.
    • What’s not available during the read-only period?:  Commenting on news stories, content that requires logging in before viewing, content editing on the main Middlebury website.

 

  • The hosted Hyperion and Banner applications, including Banner INB and SSB, will be updated and unavailable between 8am and 9am EST. The development environments for those services will be unavailable between 9am and 10am EST.

 

  • Middfiles, which includes Orgs, all Classroom, and home directory folders, will be rebooted and unavailable for approximately 10 minutes starting at 8am EST.

 

  • The Exchange email environment will undergo resource reallocations impacting 8 servers. The email environment is sufficiently redundant that we expect no impact to availability during this maintenance.

 

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

ITS system and network maintenance plans over the 2014 Holiday Break

Categories: Midd Blogosphere

Dear Colleagues,

 

Every year we take a brief period during the Holiday Break to perform needed maintenance and upgrade of our infrastructure and core systems. Below is a description of what we are planning for December 20th,21st, 22nd and 23rd, and how it may impact you.

 

  • Exchange email environment will be upgraded from version 2010 to 2013
  • The new 2013 cluster is already built and integrated together with our 2010 cluster.
  • We will migrate student mailboxes beginning Wednesday, Dec 17th through Friday, Dec 19th. Faculty & Staff mailboxes will migrate beginning Saturday, December 20th through Sunday, December 21st.
  • Once all of the Outlook accounts have been migrated, you will see two or more restart messages. If you have access to multiple mailboxes, you will see more restart messages. Except for that, we do not anticipate any other impact for you.
  • The interface for webmail will be changed, with an updated design that is reflective of the Outlook 2013 interface.
  • We have identified an issue that relates to the existence of both Exchange 2013 and Exchange 2010 servers that affected relatively small percentage of mailboxes, however many of them belonging to Faculty.  These mailboxes were not accessible for much of Monday, Dec 16th, to resolve this problem, these mailboxes have been migrated to Exchange 2013 ahead of schedule.  Our sincere apologies for the inconvenience this cause these individuals during this transition.

 

  • PaperCut printing management service will be upgraded on Sunday, Dec 21st between 8 am and Noon. There will be several short printing service interruptions during this window.

 

  • Wireless Infrastructure Upgrade on Monday, Dec 22nd between 9 and 11 am.

o   During this upgrade all wireless access points on campus will be rebooted, resulting in up to 15 minutes of wireless connectivity downtime throughout the campus, Bread Loaf and the Snowbowl.

 

  • Middlebury core network routing changes on Tuesday, Dec 23rd

o   We will be adjusting parts of our core network and routing between 8 AM and Noon. There will be 30-45 minutes of network service interruptions to McCardell Bicentennial Hall and separately, 30-45 minutes of network service interruption to residence halls on the North side of campus.

 

  • Internet related outages – starting at 2pm on Tuesday, Dec 23rd

o   Beginning at 2pm, we will be testing Internet and network component failover procedures. We expect there will be 3 to 5 interruptions of Internet connectivity to and from the Middlebury network, each lasting about 5 minutes.

 

Thank you for your patience and support as we perform these necessary upgrades,

Systems Maintenance this Sunday Morning

Categories: Midd Blogosphere

During our regular maintenance window this Sunday, Dec 7th between 6 and 10 am we have the following activities scheduled:

 

  • One of the Middlebury Internet Service Providers has scheduled network changes that will result in the circuit going down for a few minutes. We have sufficient redundancy in providers that impact to the Middlebury network should be negligible.
  • Our Active Directory servers will be rebooted for regular maintenance. Customer facing services will see no impact. Admin login access to some Linux based servers will be unavailable for the duration of a server reboot.
  • Our DNS and DHCP servers will be rebooted for regular maintenance. We have sufficient redundancy that there should be little to no impact.
  • There will be equipment added to the network closets to increase client capacity at the Middlebury Marble Works offices. Network access in those offices will be unavailable while the equipment is offline for expansion.

 

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