Offline page as last resort with GTM
We have a requirement to present a service unavailable page when all GTM pool members are down, but can't really afford to dedicate new IP addresses at each site just for this.
There are two independent LTM sites, one GTM pool with the two LTM virtuals, using Global availability. My thoughts are to have each VS have an irule which responds with the site down page if no LTM-pool members are available.
Can someone suggest an efficient way to get the GTM to revisit the original pool members as a last resort, when the virtuals are marked red?
