DNS Service Throttle

My team recently encountered an issue with the Discovery Service where we received the following error in the console:

[Resolver Throttle] <ip here> has hit the max hit limit (250) and is being throttled.

After investigating, we discovered that our API was sending an excessive number of requests to a third-party service, which triggered the throttle in the Discovery Service. This throttling then impacted other API requests in our environment.

The Cycle team explained that the throttle is in place "to prevent getting banned from lookup services like Google's domain servers or other public nameservers." The throttle limit resets every five minutes.

We’ve since resolved the issue on our end, but I wanted to share this experience in case anyone else encounters a similar problem. Hopefully, this helps someone avoid the same situation.
