All bets are of course off if you're coming from a non-NATted (or only partially NATted) network, but most residential customers will only have the one external IP. We have two but only because we've got a backup ISP -- I had my phone on that connection and didn't see even a holding page :(
There have certainly been suggestions that some ISPs were having more trouble than others yesterday, and that some of the problems may have been DNS-related (and therefore, yeah, possibly involving caching to servers which weren't reachable)
