A Wapping crash, then silence

If anyone out there has been wondering about the deafening electronic silence from News International hacks over the past 24 hours, apparently their email system has been down since yesterday afternoon. Monkey hears IT has been reduced to texting updates to NI staff. "Have you tried turning it off and on again?" or "email still f***** :(", possibly. Is Rupert installing the great firewall of Wapping, as well as a paywall?
