Minor update

Pretty quiet the past few days.

We had to take both clusters down for about 15 minutes while telecom upgraded the IOS on the switches servicing the clusters. That went with nary a hitch. The first part of this was done a few weeks ago, so this should be the last time we have to do this for them for a while.

We're preparing to get the cluster and backup servers onto a gig-E blade. That'll improve things! For a while all the student services were housed on one cluster-node, and that was averaging between 15-20% utilization on 100-meg Ethernet. We have slack, but it getting into the area where performance degradation starts creeping in.
