How to Hide Origin IP When a Card Game Server Is Attacked: Contain, Change IP, Encapsulate Access in Three Steps
When the origin IP is exposed, attacks bypass perimeter defenses and hit the server directly, sometimes leading to ISP blackholing. This article presents an operations-driven sequence: first contain the breach with security group whitelisting, then close all leak channels such as hardcoded client IPs, DNS history, and outbound callbacks, then change the public IP and move core nodes into a private network, and finally encapsulate access for long connections and web traffic separately through game shield and high-defense reverse proxy, with a mandatory post-change verification checklist.
How to Choose Between Game Shield and High-Defense CDN: 4 Criteria Determine Feasibility and Defense Depth
The choice between Game Shield and High-Defense CDN depends on business protocol layer, client form, defense depth requirements, and origin exposure risk.
How to Restore a Domain Blocked by WeChat Without Changing Domains: Diagnosis, Appeals, and Fallbacks
If a site won't open in WeChat but works in external browsers, it's likely an application-layer block by Tencent's security database. This guide covers the operational order: distinguish WeChat blocks from DNS poisoning, identify soft vs. hard blocks, complete remediation, file a webmaster appeal, use backup channels like Tencent Security Center and email, and implement UA-based fallback during the appeal process, plus when to consider professional domain unblocking services.
How to Recover a Domain Blocked by DNS Poisoning: Layered Diagnosis Before Cleaning or Reverse Proxy
A domain suddenly inaccessible in mainland China may not be DNS poisoning — this article provides a four-step check to confirm resolution-layer spoofing, rules out more common causes, and presents two recovery paths: temporary client-side self-rescue (DoH/DoT, hosts) and business-side recovery without changing the domain (poisoning cleaning, reverse proxy/high-defense CDN), plus post-recovery validation and recurrence monitoring.
Website Under DDoS Attack? 5-Step Emergency Recovery Sequence
When a website is being hit by DDoS or CC attacks, quick recovery depends on the right sequence: first identify the attack layer, isolate the origin server (change IP if necessary), switch DNS to a mitigation node, suppress application-layer traffic at the edge, and finally clean up lingering connections.
