Which wasn't technically saturated, since 100GB on a 20Mbit/s connection should be feasible in about 12 hours if my back-of-the-envelope math is right.
Of course, they weren't clear on details, so if they meant that the network was only up for half a day by the time they measured then it's significant.
Also I was pleased to see that they are using open/bsd with pf as the firewall.
