DuraSite CDN is a content delivery network from Accelia Inc., built and run in-house over many years. All servers sit exclusively within Japan, making it a good fit for organizations that want to keep content on domestic infrastructure and avoid currency-related cost swings.

A standout feature is the fully managed approach: Accelia’s engineers can handle everything from initial setup to day-to-day operations. An emergency phone line is available outside business hours, and getting started requires only a simple DNS change with no modifications to existing servers.

An optional DDoS protection add-on can be activated to shield origin servers from large-scale traffic attacks.

A cloud-based Web Application Firewall can be layered on top of the CDN to block common web threats such as unauthorized database queries and malicious scripts.
