That's correct, in a casual "dual WAN" setup such as this. There's no coordination between the various broadband providers. It's expected that active sessions will be lost. The hope is that new sessions can automatically be configured to work correctly, though. New outgoing sessions should automatically be routed among the ISP's that are still up. The goal is to prevent them from somehow erroneously selecting an ISP that is down, thus stalling out the new connection.
