The big use case I see are render farms. Moving terabytes of data can be made incrementally faster if the DC Is physically located closer.

Dreamworks are in Glendale and have been experimenting with cloud rendering last I heard. It's always been difficult due to bandwidth and latency bottlenecks.

Google has a new facility in the area as well: https://cloud.google.com/about/locations/la/

Unless there's better bandwidth, this will be on the order of milliseconds.

Its mostly higher bandwidth from being closer to source. Latency is definitely improved but so is bandwidth if you are in peered in the same exchange. Peek bandwidth is going to be much higher, especially if you are pulling/pushing north of 10G.
