Updatable Objects and DNS queries

[David_C1]

In our lab environment, we have created two rules which use four different Updatable objects :

Azure Services

Okta Services

Office365 Worldwide

Office365 Worldwide Services

Once these rules were added, our gateways started submitting a large amount of DNS queries, upwards of 435,000 an hour. That's a lot of queries, it looks like most domains are queried 4 times a minute.  Is this expected behavior, and is there any way to change some setting(s) to decrease this number?

Thanks,

Dave
