Why regional reach matters in Brazil
Brazil is a continental-sized market with thousands of regional ISPs. Many CDN deployments are concentrated in São Paulo, Rio de Janeiro and Fortaleza, which leaves users in other regions consuming content from distant caches through IP transit or remote peering.
For CDN providers, reaching this long tail with proper capillarity is operationally complex and often economically hard to justify through standalone deployments. OpenCDN provides a neutral shared-infrastructure model for placing caches closer to regional IX.br locations.
What is OpenCDN?
OpenCDN is a neutral, non-profit collaborative initiative operated by NIC.br and CGI.br that provides shared technical infrastructure for hosting CDN cache servers at IX.br Internet Exchange Points across Brazil. Participating CDNs install and operate their own cache servers within this shared infrastructure, with operational costs shared among participants — and waived in several locations through institutional partnerships.
Once installed, cached content is delivered directly to the ISPs connected to each IXP via a bilateral BGP session with AS61580, the OpenCDN Autonomous System — reaching Brazilian users with very low latency and no additional transit costs.
Benefits for CDN providers:
- Colocation infrastructure and IP connectivity support provided at no cost in most cases
- Instant reach to a large number of Brazilian ISPs through a single BGP session
- Ultra-low latency delivery — content served locally inside each IXP
- No need to negotiate individual peering agreements with each ISP
- Infrastructure operated by NIC.br, the same neutral organization that runs IX.br
In most locations, CDN participation carries no direct cost — shared operational expenses are borne by ISP participants, not charged per CDN deployment.
OpenCDN in operation
OpenCDN is already active in Belo Horizonte, MG, Belém, PA, Brasília, DF, Manaus, AM, Recife, PE and Salvador, BA, with extended locations in Caruaru, PE, Feira de Santana, BA and Goiânia, GO.
Each location provides a shared operational environment for regional CDN deployment, allowing one deployment to reach multiple ISPs participating in the local IX.br IXP through infrastructure operated by NIC.br.
