What is cufwUrlfAllowModeReqNumAllowed?

This Counter64, in Requests, counts URL access requests that were allowed specifically because the URL filtering server was unavailable at the time, accumulated since the last reboot. An admin watching this counter can tell how much traffic is passing through unfiltered due to 'fail-open' allow-mode behavior during server outages. A spike here coinciding with a known filtering-server maintenance window would explain a temporary rise in unfiltered web access.
