From what I've heard, most of the cellular networks and wireless
infrastructure is down. Thats what I heard recently, I don't know if
anything has come back up. On a related note, whats going on with JUSCN,
which has a landing in Shima? I heard there was damage, but I don't have
hard facts as of yet.

Is it too soon to start to compare and contrast how voip
held up vs. tdm? Back in the old days circa mid to late
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?
