The following essential network maintenance activity is planned for this Sunday morning that will result in extended service interruptions throughout the campus.
Between 6:30 and 7:15 am the network core’s components will be upgraded. While all of the components of the network core are redundant, not all parts of the network throughout the campus have a path back to both sides of the network core. As a result there will be a 20 – 30 minute network service interruption for the majority of buildings on campus.
Between 7:00 and 8:15 am critical network aggregation switches that connect campus buildings and server farms to the network core will be upgraded. This will result in a complete interruption of network connectivity of approximately 30 minutes throughout the campus. This includes access to the College’s primary web sites, Email, MiddFiles – all systems hosted at Middlebury.
Between 7:45 and 9:00 am our border gateway routers and other components that connect the network core with the Internet will be upgraded. We expect four 3-5 minute periods where Internet routing will be in flux and expect transient loss of Internet connectivity for the Middlebury campus. During these four 3-5 minute periods, the VPNs with MIIS and Ellucian may be interrupted briefly, this would impact reaching Banner SSB and INB.
These network upgrades are essential and must be completed in a timely manner. We appreciate your patience as we strive to keep our network operating optimally.
