Setup:
Multi AZ ELB hostname: myapp.elb.amazonaws.com Hostname resolves to IPs (Round Robin): 1.2.3.4 and 5.6.7.8
In the event that the LB service behind IP 1.2.3.4 fails, does AWS remove the IP 1.2.3.4 from the hostname RR rotation or does it simply keep the same IP (i.e. virtual) but points to a healthier LB service?
Documentation doesn't seem to discuss this detail. Hopefully someone here knows :)
