Re: AW: ams-ix - worth using?

Without getting in the middle of the eternal contest over who is better, LINX or AMS-IX (each has its own advantages and disadvantages), the AMS-IX website says 165Gbps, the LINX website says 95Gbps (actual publicly switched traffic), and the DECIX website says 71Gbps. Some portion of the AMS-IX traffic seems to be Dutch-specific content that stays in the country, but there is plenty of global traffic there too.
There is no "fair" stat, since you cannot quantify an IX into a single dimension.
Equinix Ashburn almost certainly carries more traffic through the building than AMS-IX carries, probably by many times, but that stat is not published as most of the traffic is over PI.
The AMS-IX member list includes people hooking up for VoIP peering and other things at Kbps instead of Mbps or Gbps.
There is a building in Seoul, South Korea, which some claim passes multiple terabits per second over private peering. (Honestly, I don't believe that number, but it's been claimed.)
The numbers mean what the numbers mean. AMS-IX has more traffic flowing over their public switch infrastructure than any other public exchange in the world. This means only and exactly that AMS-IX has more traffic flowing over their public switch infrastructure than any other public exchange in the world - nothing more, nothing less.
If you base your buying / peering requirements on one dimension of an n-dimensional decision matrix, you are probably not choosing optimally.
All that said, AMS-IX is an outstanding IX. A network with significant European traffic is almost certain to find peering at AMS-IX beneficial. But the same is true for other exchanges (e.g. LINX).
