If we are retrieving a list of IP's via Dynamic Block List to Allow and/or Deny traffic, what would happen if the web server hosting the .txt file is inaccessible during a refresh? Would the DBL object lose all of the IP addresses and render the rule using it useless?
No, it'll use the previous refresh output results(If that was successful) or the previous cached output.
The Palo Alto tech doc noting the cache usage behavior.
