curl CDN diagnostics: HTTP headers, caching, TLS timing

Leave a reply
Comprehensive Diagnostic Methodologies for Global Content Delivery Networks via the curl Command-Line Utility Modern CDNs hide enormous complexity behind clean, fast responses. Anycast routing, TLS termination, cache layers and security policies can all fail in subtle ways. In this article we focus on using curl as a transparent, protocol-level diagnostic tool that lets engineers at CDNsun customers and beyond observe, test and optimize end-to-end CDN delivery with surgical precision. Transparent HTTP/S Diagnostics for CDN Routing and Caching At the heart of CDN [...]

How TLD DNS latency shapes CDN TTFB and Core Web Vitals

Leave a reply
The DNS performance of top level domains is a hidden but decisive factor in global content delivery. Before any CDN edge or web server can respond, resolvers must traverse the DNS hierarchy and contact TLD nameservers. In this article we examine how modern TLD infrastructure, latency profiles and security features affect Time to First Byte and how to choose TLDs that support, not limit, your web performance strategy. Top level domain latency as a performance lever The DNS lookup path to [...]

Low Latency HLS with CDN: The Ultimate Production Guide

Leave a reply
The Ultimate Guide to Low-Latency HLS with CDN: From Theory to Production Live streaming for sports, betting, gaming and auctions demands delays under a few seconds. Traditional HLS cannot keep up, often adding 20–30 seconds of lag. Low-Latency HLS (LL-HLS) closes this gap to around 2–3 seconds while still leveraging global CDN infrastructure. This guide explains how LL-HLS works and how to implement it end‑to‑end with a CDN. Low-Latency HLS Fundamentals: Why CDNs Matter Standard HLS was designed for reliability and large‑scale [...]

CDN Traffic Steering Guide DNS Anycast Layer 7 Multi CDN P2P

Leave a reply
Choosing the right CDN architecture is no longer just about “having a CDN.” Today, providers use very different traffic steering technologies to decide which edge server (or even which peer) will serve each request. In this article we walk through the main models—DNS-based, Anycast, application-layer steering, multi-CDN, and P2P CDNs—explaining how they work, how they differ, and where each shines.   Modern CDNs are primarily differentiated not only by their footprint or capacity, but by how they decide which edge node [...]

CDN: The Technical Backbone of Modern Live Streaming (And Why Latency is the Ultimate Challenge)

Leave a reply
Welcome to the CDNsun blog. As a Content Delivery Network (CDN) company specializing in high-performance delivery, we understand that modern live streaming is less about content and more about complex, distributed systems engineering. The internet's demand for real-time video has exploded, transcending simple entertainment to become critical infrastructure for commerce, education, and global events. This article dissects the role of the CDN in fulfilling these demands. It explores three technically challenging live streaming scenarios, demonstrating how the CDN architecture—with its [...]

Advanced HLS Streaming Optimization with CDN for Global Delivery

Leave a reply
Delivering high-quality HLS streaming to viewers worldwide is more than encoding video—it’s about how efficiently your CDN stream distributes content. Advanced strategies for segment delivery, caching, and edge optimization are key to minimizing latency, preventing buffering, and scaling efficiently. HLS divides video into small chunks (2–10 seconds). When a viewer requests a stream: The player requests the master playlist (.m3u8). Based on the viewer’s bandwidth, the appropriate variant playlist is selected. Segments are requested sequentially, typically from [...]

Why Mobile-Friendly Control Panels Are Essential Today

Leave a reply
Why Mobile Control Panels Matter More Than Ever Technology has changed the way we interact with the world. Not long ago, managing important online services required sitting down at a desk, opening a computer, and logging in. Today, our phones have become the primary gateway to almost everything — from communication and navigation to shopping and banking. It feels natural that managing crucial web services should follow the same path. Control panels are no longer just back-office tools. They are the [...]

HLS vs DASH: Choosing the Right Protocol for Live Streaming

Leave a reply
The landscape of live streaming has evolved dramatically over the past decade, with two major adaptive bitrate streaming protocols dominating the market: HTTP Live Streaming (HLS) and Dynamic Adaptive Streaming over HTTP (DASH). As content delivery networks continue to play a crucial role in delivering seamless streaming experiences, understanding the nuances between these protocols becomes essential for developers, content creators, and streaming service providers. In this comprehensive guide, we'll explore both protocols, their strengths, weaknesses, and how they integrate with [...]
