Sorry I don't think I made my question clear. By
"work" I mean _eventually_. I know the existing
connections will break and I know it may take several
minutes to establish new connections; that's okay. The
key issue is using a _static_ IP assigned by the ISP
whose drop is temporarily down. And the question
should not have been whether or not it will work, but
rather _how_ to make it work. In other words, what do
other folks with a _static_ IP and _multiple_ ISPs do?
thanks!
