1. A non-transitory computer-readable storage medium storing one or more sequences of instructions for recovering or restarting an execution instance, which when executed by one or more processors, cause:
in response to detecting that a particular execution instance, in which an optical line terminal (OLT) and/or broadband network gateway (BNG) software application in a passive optical network (PON) executes, has failed, performing:
restarting the particular execution instance having only downstream service flow classifiers and entries of an access control list for the particular execution instance to support voice calls; and
after restarting the particular execution instance, over time adjusting the configuration of the particular execution instance to add one or more downstream service flow classifiers or access control list entries.
