Decentralized with respect to connectivity. If a construction crew cuts a fiber bundle routing protocols will route around the damage and packets keep showing up at the destination. Or, only a localized group of users will be affected. That level of decentralization is not what we have at higher levels in the stack with AWS being a good example.
Even connectivity has it's points of failure. I've touched with my own hands fiber runs that, with a few quick snips from a wire cutter, could bring sizable portions of the Internet offline. Granted that was a long time ago so those points of failure may no longer exist.
