Domain mapping stopped working

OK - I have around 150 domain mapped domains --

minimum of 3 sets per city --
classifieds.actioninatlanta.com mapped to atlantaclassifieds.theactionisociety.com
realestate.actioninatlanta.com
mapped to atlantarealestate.theactionisociety.com
actioninatlanta.com mapped to atlantabusiness.theactionisociety.com

Now I have those same 3 sets for each major city --- and everything was fine --

Not sure when it started happening but I believe it has been within the last 2 weeks -

All of a sudden every cities classfieds domain shows invalid and when I try to domain map them again -- it says that the domain does not exist - see attached -- and every one of the classifieds sites -- says the same thing -- any ideas
