My manager was on the Tokyo airport, when the earthquake started. We had a chat yesterday about this – he is back home in the meantime – and he told me that he was very surprised that, while the phone network broke Internet still worked and he was able to call his wife immediately after the first shock.

Now, it still seems to be the case: Japan's Internet Largely Intact After Earthquake, Tsunami – fairly impressive.

BTW: Our Chief Security Advisor in Japan is well as is his family, luckily.
