Not applicable when you're mostly just one campus, unless you want to discuss
per-building feeds. Most of our buildings have 1 or more 1G uplinks to a 10GE
core network, and some larger ones have their own 10G uplink. There's a few outlier
buildings that have a dozen or so people that still have 100M uplinks.

We're working on deploying 1G to the desktop. Some buildings are going faster
than others - the ones we wired first are now the hardest, because there's a
lot of Cat-3 in them. The later ones that already have Cat-6 will be easier.
With something like 120 buildings to do, it's going to take a while.
