To preface: I am not qualified to talk about this in the slightest. > Unfortunately, we discovered that a subset of services that were supposed to be on the high availability cluster had dependencies on services exclusively running in PDX-04 What do you mean you discovered?

And surely, since you had been "implementing" this for four years now, you've TESTED what would happen if one of the three DCs went completely offline, right???
