Beyond Acceleration: When Video Services Face a 'Dimensional Strike,' Has Your CDN Built a Line of Defense?
A video CDN is more than an acceleration tool—it is a line of defense for your business. Facing hotlink theft, malicious bandwidth consumption, and CC attacks common in live streaming and VOD, RockCloud combines high-performance delivery with multi-layered security to build a robust video streaming architecture.
DNS Pollution Cleaning: Say Goodbye to the Self-Salvation Myth of Making Users Change DNS, and Build a Server-Side Recovery and High-Defense Accelerat
When your business encounters cross-network spoofed responses, BGP route hijacking, and recursive cache poisoning by regional ISPs, instructing end users to change public DNS or configure DoH is completely ineffective in recovering lost public traffic. This article dissects the mechanisms of DNS pollution and cache poisoning from the underlying resolution chain, and explores how RockCloud's DNS pollution cleaning, seamless 301 redirects, CN2 three-network direct connection, and high-defense CDN architecture can achieve in-place business recovery and long-term anti-hijacking without changing domain names or modifying NS.
Why Domain Interception Recovery Can't Rely Only on Appeals or Changing Domains: A Closed-Loop Architecture from In-Place Recovery to Preventing Repea
When facing DNS poisoning, regional ISP blocking, and WeChat/QQ red-shield interception, relying solely on manual appeals is slow and has a low success rate, while abandoning a domain for a new one causes APP API disconnections and wasted ad spend. This article analyzes the technical causes of frequent 'secondary interception' after domain recovery or switching, and combines RockCloud blocking/poisoning recovery, high-defense CDN, and intelligent WAF to provide a closed-loop solution for in-place recovery without changing domains and long-term anti-blocking protection.
No-ICP CDN Migration and Second-Selection Guide: Saying Goodbye to Evening Peak Stalls, Misblocked APIs, and Hidden Renewal Bills
Many teams hosting their origin servers overseas are forced to switch CDN providers after their first no-ICP CDN causes mainland China evening peak stalls, misblocked login and payment APIs, huge traffic bills after attacks, or domain blocking. This article breaks down the second-selection criteria for no-ICP high-defense CDNs across four dimensions: China-ring three-network direct-connect architecture, fine-grained smart WAF allowlisting, fixed peak billing, and NS-free smooth switching.
Game Shield Private Protocol Encapsulation and Full-Protocol Forwarding: A Protection Architecture Against TCP/UDP Non-Standard Port Attacks
As game attacks evolve from traditional traffic floods to precise probing and mixed attacks against TCP/UDP non-HTTP interfaces, standard web protection alone can no longer cover core combat and multiplayer logic. This article provides an in-depth analysis of how Game Shield builds a full-protocol game defense line through private protocol encapsulation, distributed edge node forwarding, and seamless switching mechanisms without modifying the origin server.
