Reduce Spike in DNS Queries

A few times per week, we’re seeing a spike in NOERROR DNS queries, which temporarily makes our site unresponsive (for a couple minutes). To give you an idea of scale, it may go from an average of 100 per minute to 10k for a minute…

Is there a Cloudflare tool we can deploy to help us manage or throttle DNS queries to help prevent this from happening?

Thanks!
