但集中式网络基础设施在AI时代面临严峻挑战。随着数字化进程的加速，互联网对少数关键基础设施 的依赖程度日益加深。这种高度集中的架构虽然提高了效率，但也使得整个系统变得异常脆弱。一旦核 心节点出现问题，就可能引发连锁反应，导致大范围的服务中断。 近日，网络安全与基础设施服务商Cloudflare遭遇自2019年以来最严重的服务中断事件，故障持续近5小 时，导致ChatGPT、社交媒体平台X等多家网站部分用户无法正常访问。 值得注意的是，此次事件并非网络攻击所致，而是由配置文件异常引发系统崩溃。 Cloudflare在随后不 久发表声明："Cloudflare已察觉并正在调查一个影响多个客户的问题：大范围500错误，Cloudflare仪表 板和API也出现故障。" 该事件再次引发业界对集中式网络基础设施可靠性的广泛讨论。 Akamai亚太地区及日本安全技术和战略总监Reuben Koh在接受《中国经营报》记者采访时表示，问题 的核心在于集中性风险，现代技术栈的复杂性意味着没有服务商能够完全避免故障。此次事件进一步证 明，当核心基础设施出现故障时，可能会拖累部分互联网生态系统。 实际上，集中式网络基础设施的崛起源 ...
