I thought this was about consolidation of email providers so your email never leaves a single datacenter:

"10 years ago we couldn't send an email 500 miles, but these days we can't send it 500 miles because it just routes internally."

Too bad, I think that would have been more interesting to read.

This is the first roadblock the author runs into - lots of universities ping at <2ms, likely because everyone's on the same datacenter.
