On any Server Trafficweb origin you can add a global CDN — cache assets and video at the edge for lightning-fast loads worldwide, lower latency and dramatically reduced origin load.
A content delivery network (CDN) is a cache that lives close to your users — and the Server Trafficweb CDN add-on is what you attach to your existing origin to give every visitor that experience. When a viewer in Mumbai requests a video segment that originally sits on your streaming server in Amsterdam, the CDN serves the answer from a nearby edge node, not from the origin all the way across the world. The first request travels far; every subsequent visitor in the same region benefits from a cached, milliseconds-away response. Across thousands of visitors the savings compound: faster pages, dramatically lower bandwidth bills, and an origin that can focus on dynamic, personalised work.
Modern CDNs are not just for static assets. Our CDN accelerates HTML, CSS, JavaScript, images, fonts, video segments (HLS and DASH), large downloads and selected API responses through edge caching, route optimisation, modern transport (HTTP/2 and HTTP/3) and TLS termination at the edge. Edge nodes are spread across continents so visitors in Western Europe, North America, the Middle East, Asia and beyond hit a cache that is close to them — not a server somewhere on the other side of the planet that adds 200 ms to every byte.
The benefits are concrete and measurable. Page speed jumps because static assets load from the edge in single-digit milliseconds. Core Web Vitals improve, which Google considers in search ranking, so SEO benefits along with UX. Origin bandwidth drops because cached responses never touch your server, saving real money on transfer bills. Video starts faster, seeks faster and buffers less because HLS and DASH segments are pre-positioned near viewers. Resilience goes up because even if your origin is briefly unavailable, cached content keeps serving from the edge.
For streaming, IPTV and download-heavy operations a CDN is the difference between a smooth launch and a viral disaster. A live event can spike from a few hundred to tens of thousands of concurrent viewers in minutes. Without a CDN your origin saturates and everyone buffers. With a CDN the edge absorbs the surge and the origin barely notices. Pair the CDN with higher uplinks on the origin, DDoS protection in front of both and load balancing across origin replicas for a complete, scale-ready setup.
Key Benefits
Static assets, fonts and video segments cached at nodes close to your visitors for near-instant loads — wherever in the world they sit.
The CDN absorbs most repeat traffic so your origin stays responsive even when a launch goes viral. Origin bandwidth bills drop significantly.
Edge delivery, HTTP/2 and HTTP/3 push LCP, FID/INP and CLS into the green — measurable in Google's ranking signals and bounce-rate analytics.
HLS and DASH segments cached at the edge mean faster starts, smoother playback, fewer rebuffers and faster seeks on live and VOD content alike.
TLS termination at the edge with HTTP/2 and HTTP/3 plus optimal cipher suites — no manual cert juggling on every origin.
Cache by URL, by tag, by query parameter; purge instantly by URL, tag or globally; bypass for personalised content with fine-grained rules.
Block or allow visitors by country, ASN or IP range to keep abuse out and trusted partners in — all at the edge, before your origin sees a packet.
Sits naturally with DDoS protection, load balancing and origin bandwidth upgrades for a complete scale-out plan.
Built for real workloads
Marketing pages, blogs, news sites and e-commerce stores see lower bounce rates when pages load fast around the world. SEO benefits compound over time.
Cache video segments at the edge so global viewers see fast start times and smooth playback. Pair with our VOD server for the complete stack.
Edge delivery for IPTV catch-up, replays and on-demand content reduces origin load and keeps live streams responsive for every viewer.
Accelerate large binary downloads, game patches and OS installer mirrors with edge delivery — users get fast installs and you get predictable bandwidth costs.
Cache idempotent API responses and tune cache headers so mobile apps feel instant. Public read endpoints often see 10×+ throughput improvements.
Simple. Predictable. Powerful.
Add a CDN hostname for static assets, or front your origin completely with the CDN as a reverse proxy. Either model is set up in minutes.
Configure cache headers, TTLs and URL/tag rules so the CDN knows what is safe to cache and for how long. Sensible defaults get you most of the way.
First requests in each region populate the edge cache. From there on, subsequent visitors in that region are served from the edge in milliseconds.
When you update content, purge by URL, tag or globally. Purges propagate across the edge in seconds so updates are visible worldwide quickly.
Use hit rate, latency and bandwidth analytics to refine cache rules and squeeze even more performance out of the CDN over time.
