Scheduled Service Change: Biannual Network Redundeancy Testing
Testing of core campus data networking links is expected to have no impact. Testing of WAN links will result in periods (30-45 seconds) of intermittent connectivity to external sites as routing protocols converge.
There is no workaround for this issue
CIT Network & Communications services will be performing network redundancy testing on the core campus data network connections and wide-area connections between 4am and 8am on Saturday, January 29th. During this window, connectivity from Cornell to/from external sites (Internet. Internet2, NLR, etc.) will be intermittent as routing protocols converge around failed links and redundancy is tested.
