Overview
BitGravity was founded in 2006 as a pioneer in HD content delivery, known for its proprietary BitGravity Delivery Network (BDN) and groundbreaking HD video streaming technology. Acquired by Tata Communications in 2010, BitGravity's technology fully integrated into Tata Communications' global network infrastructure, becoming a core asset in the CDN acceleration space.
Built on a distributed edge node architecture, the platform supports HTTP/HTTPS static acceleration, large-scale video streaming, dynamic content acceleration, and API request optimization. Its proprietary transport optimization and smart routing maintain low latency and high throughput, especially for video platforms, online education, and media organizations, with built-in DDoS protection, Token authentication, and Referer anti-hotlinking.
As part of Tata Communications' enterprise portfolio, BitGravity serves large media groups, telecom operators, and multinationals. With no mainland China nodes and limited self-service, it suits customers with dedicated ops teams; smaller sites should evaluate Cloudflare and similar self-service options.
Key Strengths
- Global brand and carrier-grade infrastructure: Backed by Tata Communications with over USD 20B annual revenue, Tier-1 backbone, 100+ edge POPs, and SLA-backed enterprise CDN service.
- Leading HD video delivery: Supports adaptive bitrate (ABR), HLS/DASH, low-latency live (LL-HLS and WebRTC), and 4K/8K end-to-end delivery with heat-aware smart edge caching.
- Enterprise-grade security: Built-in L3/L4 DDoS protection, Token authentication, signed URLs, Referer/IP access control, plus optional WAF and Bot management.
- Flexible custom support: 24/7 support with dedicated account managers, cache tuning, routing policies, performance baselining, and custom SLA.
Product Ecosystem
Video Streaming Delivery (Core)
VOD and live acceleration with 4K/8K and low-latency live.
Static & Dynamic Acceleration
HTTP/HTTPS static and dynamic content acceleration.
Enterprise Security
DDoS protection, Token anti-hotlinking, and DRM integration.
Custom Services
API integration, dedicated account manager, custom SLA.
Limitations
- Low self-service, high entry barrier: No public self-service signup or console; requires sales negotiation and contracts, with weeks-long onboarding and no real-time usage dashboard.
- No mainland China nodes: Domestic users face 100-300ms cross-border latency; consider dual-line deployment with Aliyun CDN or Tencent Cloud CDN.
- Opaque pricing: Enterprise custom quotes starting at thousands of USD/month with bandwidth and add-on costs.
- Limited ecosystem integrations: Few prebuilt CMS plugins, framework middleware, or open-source cache plugins; higher integration and migration costs.
Use Cases
- Large video streaming platforms (★★★★★): VOD, OTT, and live platforms; pair with video streaming acceleration best practices.
- Multinational global site acceleration (★★★★): Consistent experience via Tata's global network with multi-region deployment.
- Online education and training (★★★★): HLS/DASH adaptive bitrate ensures smooth playback across bandwidths.
- Media/news portals (★★★): Global acceleration of images, CSS/JS, and multimedia with Token anti-hotlinking; see the CDN setup guide.
- Large enterprises and government (★★★): Enterprise contracts and dedicated support for higher security with defense-in-depth.
Pricing

FAQ
- Is BitGravity still an independent brand? Its CDN technology and brand now operate as part of the Tata Communications CDN product line, with onboarding and delivery managed by Tata Communications.
- Is it suitable for personal blogs or small sites? No; it targets the enterprise market with no self-service signup; choose Cloudflare's free tier or Bunny CDN instead; see the CDN provider selection guide.
- How fast is it in mainland China? No domestic nodes, so cross-border latency applies; use domestic CDNs or a dual-line architecture for Chinese audiences; see the multi-CDN load balancing setup.
- How can video hotlinking be prevented? Token signed URLs, Referer/IP allowlists, and DRM integration; see CDN security features.
- Can it be used in a multi-CDN setup? Yes, via standard CNAME/NS and smart DNS for load balancing and failover; see the multi-CDN load balancing setup.
