Scheduled Service Change: Redundancy testing, Campus Backbone and Wide-area links
Testing Campus backbone link failures should not impact network connectivity. Wide-area testing will result in brief interruptions (30-45 seconds) to external service providers as routing protocols converge around the failed links.
There is no workaround for this issue
On Saturday, Nov 3, 2012, between the hours of 5am-7am, CIT-NCS will be conducting biannual network redundancy testing on the Campus Backbone and wide-area links. During this window users may experience multiple (4-5) brief (15-45 second) periods of intermittent connectivity to sites external to Cornell.
