Blockcast CDN+ | Multi-CDN Redundancy Platform

Your Multi-CDN Strategy.
Fully Automated.

Automatic traffic steering across multiple CDNs —
one dashboard, less downtime, same bits at a cheaper price.

The CDN+ Advantage
Multi-CDN redundancy without the complexity

Less Downtime

When any CDN provider degrades, traffic automatically shifts to your next preferred provider. Multiple layers of redundancy mean your content stays available even when individual CDNs don't.

Configurable Switchover

Define your own routing rules across any number of CDN providers. Set priority orders, weighted splits, and geo-specific policies — traffic follows your playbook automatically.

Best Pricing

Access aggregated capacity rates typically reserved for enterprise buyers, and route traffic to regional CDN specialists in underserved markets — so you get the best per-GB price in every geography without negotiating your own contracts.

Smart Switchover
Always on the best CDN — automatically

CDN+ continuously evaluates your providers and switches traffic in real time — not just when something breaks, but whenever a better option exists based on performance, pricing, or your geographic traffic policies.

  • Switches on degradation — move traffic off unhealthy CDNs in seconds
  • Switches on performance — route to the lowest-latency provider per region
  • Switches on pricing — shift traffic to the cheapest provider in each geography
  • Geo-aware policies — different rules for different regions, all automatic
