A maintenance is scheduled for Monday, February 4th, 2008 between 11:00 pm and 12:00 am EST on one of our core routers. We have decided to replace the supervisor engine which will have the standard 1 GB memory. The VSNL uplink will only be activated after completing the maintenance (Tuesday 5th most probably). The traffic will be rerouted to other routers before the maintenance. This may take a few seconds to switch over. The supervisor engine will be replaced by another Cisco WS-SUP720-3BXL.
