I'd be careful about Big Byte on a couple points.
1. If you need or want a caged area you are forced to there lower level. While in it self isn't too bad there is no elevator down to it so you have to navigate two levels of stairs to get your racks and gear down to it. I'm speaking from experience of getting several racks and and gear down there...including completely disassembling two SAN racks.
2. Big Byte does not have redundant paths for power. All power is run in from the east side of the facility. A cut on side they are generator.
3. They do not have full redundant paths for 90% of carriers. Some carriers have run redundant paths on both the west and east sides but most don't. So one cut and you are down.
I would recommend looking at Centurlylink's Data Centers, they have two floors in the building they share with Molina Health down town. Their building is just to west of the Hyatt down down. Centurylink does have redundant paths for power and data lines (north and south sides of the building). As a matter fact they require it.
That side I will have to say if you need an infrastructure change done right away, like now, Big Byte...if you need to stay up Centurylink. Having been a customer of both.
