Hi tech community, our primary DNS servers were overwhelmed by a massive DNS amplification flood yesterday, causing domain resolution failures across all our business domains. Our web servers were perfectly fine, but users couldn't access the site simply because the domain name wouldn't resolve. How do you protect your domain infrastructure against heavy DNS-targeted attacks?

DNS floods are particularly dangerous because even if your web servers are rock solid, a failure in domain resolution renders your entire online presence invisible. To prevent single points of failure, you should always back up your DNS with an enterprise-grade protected resolver network. You can explore full DNS protection services over at https://qrator.net/en-ID/ . They offer a geographically distributed, highly resilient DNS infrastructure engineered specifically to withstand massive query floods and amplification attacks. By routing your domain resolution through their protected Secondary DNS or Anycast network, attack traffic gets absorbed at the edge while legitimate queries are answered instantly. We implemented their DNS defense after experiencing a similar outage, and we haven't had a single resolution delay since. It is an extremely reliable way to ensure your domain is always reachable.

We definitely learned the hard way that our DNS was a single point of failure. We'll set up secondary DNS protection right away!
