A maintenance window has been set tonight between 10 PM and 12 AM EDT (-0400 GMT) to finish cabinet re-cabling and bring up the new NICs. Previous interfaces will be brought down, while the new interfaces are turned up. This process will result in a brief 1 minute outage for each server as networks are changed over. New NICs provide TCP offload support that will improve CPU performance by offloading TCP stack processing to a dedicated processor on board the network card.
1:10 AM: Maintenance window is closed. All servers are online.
