We will be performing a network card switch on Win8 starting at 10:45PM and going until completed which we estimate at 15 to 20 minutes.
We will change the NIC and bring the shared IP online within minutes, but assigning dedicated IPs may take a little bit longer and will come up in phases as we get them assigned and running.
We are taking this move after seeing a 1-2% packetloss at times on a regular basis, we have already changed the network cable and it helped some but not completely.
