Case Study: Zillow improves DNS performance and uptime with Dyn

Why Zillow Moved to a Better DNS Neighborhood

Zillow, a leading US real estate website, faced significant challenges with website performance and availability due to the limitations of its previous DNS providers. Their hosting provider's DNS service lacked scalability, caused unpredictable downtime, and required a slow, ticket-based process for configuration changes. To meet the needs of its 70 million monthly users, Zillow needed a more robust and responsive solution, leading them to the vendor Dyn.

Dyn implemented its Managed DNS solution with Traffic Director for advanced load balancing and failover capabilities. This provided Zillow with consistent uptime, low latency, and the ability to make real-time configuration changes themselves. The solution eliminated unpredictable server loads and gave Zillow the confidence to proceed with plans to open a new colocation facility, ensuring continued reliability and performance for its users.
