The challenges

The web hosting company became a prime target for Distributed Denial of Service (DDoS) attacks, leading to frequent disruptions and downtime for their clients. These malicious attacks overwhelmed their network infrastructure, rendering their services inaccessible and causing customer dissatisfaction.

Over time, managing and scaling their extensive DNS zones became increasingly challenging for the web hosting company. The complexity of migrating these zones to a more robust and secure platform posed a significant obstacle, requiring a meticulous approach to ensure a seamless transition without any service disruptions.

The company had a web redirect service that allowed clients to redirect traffic from one domain to another. Managing and optimizing these redirects in a scalable and reliable manner posed a considerable challenge, demanding a comprehensive solution.

Initial DNS Struggles

The hosting company initially handled its own DNS, thinking it would save costs and provide more control. As the customer base grew, maintaining a high-quality DNS infrastructure became challenging, and DDoS attacks began affecting their reputation.
