I just came back from Japan, after being stranded at Narita Airport overnight due to the big earthquake last Friday. There really is nothing I can do to help the situation, other than to pray for my country, but as an industry professional, I will try to gather as much info as possible about telecom, mobile and internet infra/service desruption and recovery in Japan.

First, a secialist is surprised that Internet infrastructure was largely intact in Japan after the quake. I experienced it myself at Narita. After a few hours, WiFi in the airport was up and running, and I could send/receive e-mails and Twitter on my Android smartphone with no problem. It was such a relief to have a reliable communication device, as in those times, mobile phones are hard to go through and I refrained myself not to dial too many times so the circuits would not get clogged.
