The CIX is great if you're in Santa Clara, or somewhere nearby, but it
tends to be pretty slow, and isn't much use to those of us outside the
state of California.

Well over half of the connected CIX members have their main corporate offices
outside California. And I don't experience slowness in the SMDS cloud; the
packet loss rate is higher on either MAE's shared FDDI than on Pac Bell's SMDS.

Just one man's opinion. I don't speak for CIX.
