There are two sides to rcom, the mom&pop side (aka and the
partner side (Rconnection, for folks with ~25+ domains registered).   On
the mom&pop side they don't have (as far as I am concerned) a highly
redundant and distributed DNS system.  That opinion is based on a few
hours of research abt 2 years ago.  Over on the partner side they
outsource the DNS systems for their customers to eNom, which does use a
highly redundant and distributed anycast setup.  I haven't seen any
problems wrt DNS for my systems today (eNom via rcom), so I can only
presume the OP was referring to the mom&pop side of rcom.
