Even combined, no. It's north of 700 Gbps though. I am assuming they have combined S&D into the graph, though: <https://ix.equinix.com/peeringstats/userHome.do?action=home> 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. -- TTFN, patrick
