How to Implement CN2 Line Acceleration: Why a CN2 Server Alone Is Not Enough, and Why You Need Multi-Line Direct Connection and High-Defense CDN Archi
Many cross-border businesses serving mainland China find that even with expensive overseas CN2 servers, they still face peak-hour lag for China Unicom and China Mobile users, burst bandwidth limits, and blackholing under attack. This article analyzes from the underlying network routing and security architecture why decoupling the origin from the acceleration layer, and using ring-China nodes with Telecom CN2 GIA, Unicom AS9929, and Mobile CMI multi-line direct connections plus high-defense CDN, is the preferred solution balancing extreme speed and business continuity.
DDoS Defense: Building a Permanent Architecture Against Minute-Level Pulses, Layer 7 Attrition, and Compound Ransom Attacks
2026 global DDoS attacks show industrialization and polarization: over 90% of L3/L4 attacks end within 10 minutes, while L7 CC attrition lasting over 24 hours surges 380%, and over 70% of attacks use hybrid compound modes with ransom demands. This article combines latest threat intelligence to explain how enterprises can build a zero-touch DDoS defense system with always-on Anycast high-defense CDN, same-path DDoS/CC and WAF collaboration, game shield private protocol encapsulation, and origin lockdown.
How to Protect Game Servers from DDoS During New Game Launches and Major Promotions: A Defense Guide Against Pulse Floods and Simulated Player Connect
In light of recent DDoS attacks on multiple new game launches that caused login failures and disconnections, this article analyzes three new threats facing the gaming industry—second-level pulse floods, simulated real-player protocol connections, and subnet carpet bombing—and provides a practical architecture using game shield combined with high-defense CDN for full-link protection with unlimited traffic.
CDN Malicious Traffic Theft and DDoS Attacks Leading to Sky-High Bills: Pay-As-You-Go Traps and High-Defense CDN Selection Guide
In 2026, terabit-level and second-long pulse DDoS attacks and high-frequency CC theft are becoming the norm. Enterprises using ordinary pay-as-you-go CDNs face the dilemma of either bearing sky-high arrears bills or triggering bandwidth caps and active disconnection. This article analyzes the bill runaway mechanism of pay-as-you-go CDNs under attack and explains how to achieve business continuity and cost control through a fixed-peak, unlimited-traffic, integrated defense high-defense CDN architecture.
Why Non-Filing CDN Access from Mainland China Is Often Slow: Return Routes, High-Defense Scrubbing, and a No-NS-Change Onboarding Solution
Many businesses choose non-filing CDNs to skip the lengthy ICP filing process, but after launch they often face evening peak lag for mainland users, origin servers overwhelmed by CC attacks, and huge bills from traffic-based billing being abused. This article analyzes from three dimensions—cross-border return routing, same-path DDoS/CC scrubbing, and smooth CNAME onboarding—how to build a non-filing acceleration defense line that balances mainland access speed and attack resistance.
