When the primary proxy is not reachable or returns an error, the system initiates a rollover (the next
server in the list is used, until a working server replies).
When the last server in the list fails, the rollover is considered a rollback. The route advance timeout
will not take effect for 30 seconds and retransmission timers will take precedence. After 30 seconds,
the primary proxy (first in the list) will be treated as active again.
