Re: New???

I would argue that "Good" design would mean you don't have HA pairs of switches and consider that a redundant solution. This stuff can and does break, hence you're much better with DCs which aren't attached at L2 (Which I presume is the case here). Better to use L3 or DNS - but of course this is an old design, and there may well have been good reasons to follow this model at the time.
