Is it too soon to start to compare and contrast how voip

90's, there was a lot of hand wringing about whether
voip would be up to the task of dealing with a massive
emergency. Well, we certainly have one now in Japan
on almost every front imaginable.

Is voice such a small fraction of data that the larger
issues of cuts, electricity, etc make it moot, or has
there been some appreciable differences between the
two's ability to stay in usable service?


My question would be what communications methods are working *right now*
in the inital stages? (I heard cellular was down.) Past that, what's
seeing service restoration first?
