A look at Open Connect, Netflix's in-house CDN that launched a decade ago and spans 17,000 servers across 158 countries
As hundreds of thousands of households worldwide tapped into Netflix's Squid Game last month, viewers may have taken something fairly extraordinary for granted.
Context & Ripple Effects
Open Connect is the quiet counterpart to Netflix's content strategy: launched a decade ago, its 17,000 servers now sit inside major ISP networks across 158 countries, so when Squid Game topped charts in 90 countries last month, the surge was absorbed by hardware Netflix itself placed and controls. The related coverage of a decommissioned cache server with 262TB of storage shows what those ISP-embedded boxes actually look like from the inside.
The buildout also tracks Netflix's geographic ambitions — the company targeted expansion to 200 countries back in its 2015 global push, and during the pandemic it joined Equinix in expediting network and server upgrades as demand spiked. Owning the delivery layer is what lets one catalog serve that many markets at once.
First-order effects
- ISPs hosting Open Connect appliances offload Netflix traffic locally instead of paying for or routing long-haul transit, which is why the servers are embedded inside major networks rather than centralized.
Second-order effects
- Rival streamers that rent third-party CDNs face a competitor whose marginal cost per streamed hour keeps falling with each appliance deployed — pressuring their own delivery contracts and pricing.
Third-order effects
- If the pattern holds, hyperscale content platforms increasingly treat distribution infrastructure as an owned asset class rather than a purchased service, making CDN relationships a strategic differentiator instead of a commodity line item.
The trend: Streaming platforms are internalizing their own delivery infrastructure, turning CDNs from rented services into proprietary moats scaled to global content launches.
