Abstract:
A system for processing a purge request is disclosed. The purge request is received. An availability state for each content distribution node in a group of content distribution nodes is stored. Based on the purge request, one or more purge instructions are generated for one or more available state content distribution nodes of the group. Based on the purge request, one or more delayed purge instructions are queued for one or more unavailable state content distribution nodes of the group. It is determined that the one or more available state content distribution nodes of the group have completed processing the one or more purge instructions generated for the one or more available state content distribution nodes. Based at least in part on the queuing of the one or more delayed purge instructions for the one or more unavailable state nodes, it is confirmed that the purge request has been completed.
