We have 2 sites, using multi-site aggregation to load balance users betwen the 2 sites. We proactively put one site's delivery groups into maint. mode for an upcoming dc maintenance. Im getting login failures on that site with "planned maintenance" message. Shouldn't storefront respect the maint. mode and not try to issue VMs in that delivery group or am I thinking of the behavior wrong? To resolve it right now, I have disabled the icon in the delivery groups that are in MM, which should fully prevent SF from issuing a machine there.
