We consider the problem of designing PIR scheme on coded data when certain nodes are unresponsive. We provide the construction of ν-robust PIR schemes that can tolerate up to ν unresponsive nodes. These schemes are adaptive and universally optimal in the sense of achieving (asymptotically) optimal download cost for any number of unresponsive nodes up to ν.
