Got a question about unreal IRCD

if you add two link blocks in a LEAF config file, one for each hub (say there are two hubs in the regieon that the leafs are in) and add link blocks in the two hubs for the leafs.

i know that leafs can only connect to one server at once, so if one of the hubs went down, because there is a link for both hubs, would the leaf connect to the other hub?
