Switchover Can result in a loss of the sessions going through the lost ISP. If there are two translators on that ISP, the loss of one doesn't have that effect, but the loss of the last translator forces the *other* guy to send to a new prefix, and he won't have signaling to know it. But yes, the guy being translated to won't see a difference.
