could be both. the 2ks (4 sites + 1 200) in chicago have a true rats nest of ARS w/psudeo numbers for intermachine traffic. I'm recommending MFRD upgrades to support clustering, but we're not there yet. Every time they try to move another DID from one site to another, it breaks first-dig. Etc., etc. Really needs a full scrub to clean-up the db.
