What you say looks more like some giant asteroid hitting Earth, not like a technological disaster. And still less a societal collapse. Societies usually either slowly vanish into nonexistence without raising hell or just get conquered by their more agile neighbors (which is right, in my opinion)...
No, it looks like a normal implosion of a complex society. Instead of the pyramids, the nuclear reactors will be digged up some million years in the future. The maya culture disappeared immediately as well. Our society (globalized the first time in history) will disappear within weeks as soon as the network (internet and/or electricity) collapses.
I don't think it is as globalized as it might ultimately get. Electricity is not globalized at all, Internet is a distributed network at that, thus they cannot simply collapse in the way you think they would (within weeks). If ever, it surely won't look like a collapse of a unified society. I think you are crying wolf really...
