WRT 2) DOS does not require a public network; you can war dial access points or attack infrastructure to achieve the same effect. Any insight on what happened today? I'm surprised there's no failover mechanism that tries to route traffic some other way in case of a communication failure. Unfortunately BBG requires a bit more scrutiny because when their network goes down entire countries cannot finance themselves -- they had to postpone some debt sales in the UK today I read.
