Scheduled Service Change: Biannual testing of redundant backbone,Wan links
Testing campus backbone link failures should not impact network connectivity. Wide-area testing will result in brief interruptions (30-45 second) to external service providers as routing protocols converge around the failed links.
There is no workaround for this issue
On Sunday, Feb 26, 2012, between the hours of 5am and 7am. CIT-NCS will be conducting biannual network redundancy testing on 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.
