Even combined, no. It's north of 700 Gbps though. I am assuming they =
have combined S&D into the graph, though:

Given that Any2 is in the 200 range, Equinix is clearly more - more than =
all four combined.
But all the traffic on every Equinix and PAIX switch combined, is still =
lower than the traffic on any one of the three large exchanges in =
Europe. It really is all about the PNIs.
