looks Ok to me! And if the customer is willing to pay for it, I'd say
let's do it.

| What you described would work. But in general it is best to keep the
dual ring entirely within a SINGLE room. So I'd put the two concentrators
in the same room, and have all the other rooms be ICC with connections to
both concentrators.
The point is that your entire network is dependent on the integrity of
the dual ring, so it is wise not to expose it to damage. If you keep it
in one room, you minimize the risk of having that vulnerable point
damaged.

I take your point, but waht my customer is worried about is a single
point of failure. There is a real possiblity of serious flooding on
this particular site and of course there is fire etc also.
The intention of the described config was to remove a single point of
failure in these circumstances, ie within a physical location, not just
within a piece of equipment. As such, is this a sensible way to
approach the problem?

| Yes, if you are worried about the vulnerability of an entire location, then
clearly you need to branch out from two places. I believe that the number
of cases where that level of paranoia is sensible is rather small, so the
recommendation to leave the dual ring confined to the MCC still applies to
most situations. For those cases where you do go to this extreme, keep the
dual ring confined to just TWO locations, and watch closely over the cable
routing between them...
One reason why I make this point is to reduce the temptation to use "bypass
relays". These are a popular nostrum but far worse than the problem they
"solve".
