Right, I just thought about that. Even I2 folks are competing for the
limited number of connections.
I think we may have fixed a transient problem that was limiting bandwidth
unnecessarily; you'll note that the SSL outbound traffic hit 36 mb/s last

What this is basically confirming is not only is the bandwidth limited, but the number of simultaenous connections are being limited to 1500 at a time. No wonder we can't get connected. :|
