SK: The Obama administration has said that all these problems are happening because of overwhelming traffic. How good of an explanation is that?

JB: That seems like not a very good excuse to me. In sites like these there’s a very standard approach to capacity planning. You start with some basic math. Like, in this case, you look at all the federal states and how many uninsured people they have. Out of those you think, maybe 10 percent would log in in the first day. But you model for the worst case, and that’s how you come up with your peak of how many people could try to do the same thing at the same time.

Before you launch you run a lot of load testing with twice the load of the peak , so you can go through and remove glitches. I’m a very very big supporter of the health-care act, but I don’t buy the argument that the load was too unexpected.
