How We Built a 10Tbps Global Edge Network From Scratch

When we set out to build SERVERIZZ, we knew that network performance would be the single biggest differentiator. Users don't care about your marketing — they care about latency. Every millisecond matters, and we designed our entire infrastructure around that principle.

The Problem with Traditional CDNs

Most cloud providers treat networking as an afterthought. They lease capacity from third-party transit providers, add a markup, and call it a day. The result? Inconsistent latency, unpredictable routing, and zero transparency into what's actually happening with your packets.

We took a different approach. Instead of relying on a single transit provider, we built direct peering relationships with over 200 networks across six continents. This means your traffic takes the shortest possible path — not the cheapest one.

Architecture: Anycast + Smart Routing

Our edge network uses anycast routing at every PoP. When a user makes a request, it's automatically routed to the nearest data center — no DNS tricks, no geographic load balancing hacks. Just BGP doing what BGP does best.

The Code Behind Smart Routing

At the heart of our routing layer is a lightweight decision engine that runs at every edge node. Here's a simplified version of the core logic:

async function routeRequest(req: EdgeRequest) {
  const pops = await getHealthyPoPs();
  const nearest = pops
    .filter(p => p.latency < THRESHOLD_MS)
    .sort((a, b) => a.latency - b.latency);

  if (nearest[0].load > 0.85) {
    // Overflow to next-nearest PoP
    return nearest[1].forward(req);
  }

  return nearest[0].forward(req);
}

Results: Real-World Performance

After deploying to all 47 PoPs, the numbers spoke for themselves. We measured a 62% reduction in p99 latency across all regions. Our Asia-Pacific nodes saw the biggest improvement — dropping from 180ms to 43ms average for dynamic content delivery.

The key insight was that smart routing doesn't just improve speed — it improves reliability. When a PoP goes down, traffic seamlessly shifts to the next-best option. Users never notice. Our uptime hasn't dipped below 99.99% since launch.

What's Next

We're currently working on predictive routing — using historical traffic patterns and real-time telemetry to pre-position content before users even request it. Early tests show another 15-20% improvement in TTFB for repeat visitors. Stay tuned.
