No-- management actually was in touch with R and let her know (unfortunately, while she was already at work for the day!!) that they had finally identified the source of the problem, and needed to migrate some stuff this morning, anticipated about a 3h outage.... which seemed to be a little bit optimistic, since I checked about noon EDT, and still had no luck.
Anyway-- they think this will fix the problems and everything should be good to go now.
