Not entirely sure, which DC do you feel holds all your correct records 
and where is it ?

If it is not one of the 'cloud' based ones, I would clone that DC and 
sandbox the clone (but not in the cloud), forcibly demote the other two 
DC's on the sandboxed clone and then try to locally (not in the cloud) 
join another DC with a new DC name and IP. If that works, it would point 
to there being something wrong your cloud connection, if it doesn't 
work, then it looks like your domain has major problems which are beyond 
a mailing list sorting and I would then suggest you get commercial help.
