Abstract: We analyze and extend the definition of failures 
detectors to iterated communication models. In particular we 
focus on iterated immediate snapshot model, but the results 
can be extended to iterated models in general. We start by
examining the behavior of failures on iterated models and
define the concepts of implicit failure and equivalence
failure. We prove that without modification, the traditional
definition of failure detectors does not augment the computational
power of iterated models at the same rate that it does on non-
iterated models. Finally we provide new definitions and algorithms
to extent the concept of failures and failure detectors to
iterated communication models.
