Most Active Data Center?

[Guesswhat]

Most of the columns on that site are sortable. Click on the column, hold down shift and click other columns to sub-sort.

Edit: unless you mean roll up the stats to each DC, that would be a nice feature too. But can eyeball it with the sort method.

I mean group, as in group together, not order by. It would be a nice convenience feature to see the numbers in one cell pr. datacenter rather than server.
