Most populated DC?

It's not going to mean much – because we started using each datacenter at different times and some DCs were favored over others at different times for various reasons. But, for what it's worth, our deployment density in order is as follows:

Dallas

Newark

Fremont

Atlanta

Wow, Newark grew really fast then, considering it was the last DC added.

Shipping costs are cheaper to Newark… Just pile them on mikegrb's back and tell him to giddieup!

Lots of European customers seem to have moved to Newark - the ping times are noticeably better for us, compared to the other DCs.

I'm in the UK and my connectivity seems to be better to the Dallas data centre! But then, I'm on a University network ……
