Overall, I think, Internet proved to be quite reliable (we still use basically same infrastructure for decades). The key problems mainly arise from centralization (DNS) and weak/insecure protocols (BGP, HTTP). Internet 2.0 should be p2p based with end-to-end encryption everywhere, not sure if that's possible to achieve with current protocols/technologies, but torrents and Tor network are step to the right direction imho.
