Why I am able to Telnet to VIP when pool members are down ??

Why I am able to telnet to a VIP (port 443) when all pool members actually down, VS showing down as well. Could someone please explain in brief.

fortunately, virtual server answers even if pool members are down.

How can we use 

Fallback Host
or Maintenance page irules (or any other irules) if virtual server does not answer!
