This gives a baseline for estimating the power density and processing capacity of the largest (known) U.S. TLA data center. An open question: Is all that space for long term storage enabling retroactive surveillance of future enemies of the State, or is some portion of its capacity dedicated to cryptography? http://www.wired.com/2012/03/ff_nsadatacenter/all/1 _______________________________________________ cryptography mailing list [email protected] http://lists.randombit.net/mailman/listinfo/cryptography
