I just whitelisted another domain using the web interface and it appears to have worked. The domain that I originally open this thread for is still being blocked though.
ok that means there are no instances of that domain in gravity so it should no longer be blocked so im not sure why you would see any block activity on that domain now

So maps.googleapis.com is resolved to be a CNAME, that is an alias for another domain. That domain may be blocked.
What is the output of dig maps.googleapis.com
