All right the lets cut the BS .. I am the ISP and moreover failover between isps is a cool idea but not what I was trying to accomplish. I am talking about T-1s to the customer site and in this case the downtime involved is much more likely to come from failure of a hardware device. and you are sort of right ... if you were talking about regular broadband connections you might run into those sort of problems.
