Re: How long does it take for "local is best" types to recover...
Surprisingly quickly.
I've dealt with quite a few disaster recovery situations over the years.
One of them involved a flood where the customer's server and a few pc's were afflicted. Found a pc and printer that worked and got the programs and data on there so they could invoice. The telephones/ broadband had died, the outlets being below the flood level, so having Cloud would not have worked for them.
Nearest I've come to a lightning strike situation was a client who had an industrial unit next to the Euston main line. Power surges were such a regular occurrence that there was a community pressure group formed to liaise with Network Rail. Routers, switches, cheap pc's and photocopiers had all succumbed to such events. So again, the network side was part of the weakness, which is bad for Cloud.
MiFi type devices would be a solution, but I would think that throughput would be dire unless every pc had its own device.
