   @Vijay-1 thanks for addressing my comments!
   
   I pulled this PR down to run some test scenarios against it, and this case was unexpected:
   1. client IP is found in the CZF
   2. matched zone has no caches available
   3. matched zone's backupZone `list` is empty
   4. routing logic falls back to a Geo-lookup
   5. client gets 302'd to closest available cache group
   
   I would've expected item 3 to cause the client to be bypassed (if configured) or rejected. With your current code this only happens if the Delivery Service is set to CZ-only.
