In the recent years there were several passive and active measurement efforts that attempted to acquire an accurate connectivity map of the Internet. I will argue that none reached the point that allows us to safely determine what the Internet AS graph looks like. Even the definition of what constitutes a connection between two ASs is debatable, I will suggest one myself.

However, an accurate topology description by itself is not sufficient to explain many dynamic aspects of the Internet operation and we need to develop models that combine topology, constraints, and network dynamics. In this talk I will introduce our vision for creating such a model, discuss one simple example of the Internet resiliency to attacks and failures, and hint at some of our future work in this direction.
