We have detected an error on the network switch that serves the EECS data center. While we are not currently detecting any impact on network performance, experience has shown that we will need to replace a 10Gig Ethernet blade in that switch. To minimize disruption, this board is now scheduled to be replaced between 07:00-07:30 tomorrow morning. If we detect any impact on service before then, the board will be replaced immediately without warning. We regret any inconveniences this may cause.
