Workers平台：提供Serverless架构，允许在Cloudflare的全球网络上运行JavaScript或WASM（WebAssembly）代码，无需管理服务器。 当然，Cloudflare 还有一些非常不错的服务，例如托管网站的 Pages，对象存储 R2，分布式数据库D1 等，开发者体验非常不错。
知乎用户 专用设备制造业 从业人员 如果 Cloudflare 仍然无法验证你的名称服务器，尽管域名的 DNS 服务器已设置且注册局显示在全球生效，可能是以下原因： 1. 等待 DNS 传播：尽管注册局显示生效，但 DNS 更改可能仍在全球范围内传播中。
您遇到的问题是由 Cloudflare 提供的安全保护机制引发的。Cloudflare 是一家提供网站性能和安全服务的公司，它为网站提供 DDoS 防护 、 流量过滤 、 缓存加速 等服务。当访问者的行为被其安全机制误判为潜在威胁时，就会触发限制或阻止访问。 为什么会被 Cloudflare 限制？ Cloudflare 可能会基于以下几个 ...
不过 Cloudflare 的处理速度还算可以，比 AWS 上次的事故强多了： 如何看待亚马逊网络服务（AWS）于2025年10月20日突发崩溃？ 可能是什么原因导致的？ 。 也在第一时间发布了事故报告，把来龙去脉讲得非常清楚。
522 错误的本质 Cloudflare 在 15 秒内未收到源服务器的 TCP 握手响应 （SYN ACK），导致连接超时 。 你的环境中： 直接通过 IPv6 端口 可访问 → 源服务（群晖）正常运行。 但通过域名（经 Cloudflare 代理）报错 522 → Cloudflare 节点无法连通你的 IPv6 源地址。 Ping 超时的 ...
Cloudflare服务不可用可能是由于一些临时问题导致的，例如服务器维护或升级，可以尝试刷新页面或稍后再次访问，很可能问题就会自动解决了。 如果刷新页面还是无法解决问题，可以尝试修改DNS设置，具体的步骤如下： 1.
7. Cloudflare 将内容返回给用户 最终，Cloudflare 将从 Vercel 返回的博客页面内容传递回用户的浏览器。 此时，用户可以顺利加载并浏览博客网站。 用户收到博客内容：Cloudflare 将博客页面内容传递给用户的浏览器，用户最终可以看到完整的博客页面。

无线电时代， 太阳耀斑 一爆发（solar flare），短波上的电台与电报业务就大规模中断。到了 21 世纪，云服务一故障，互联网业务就大规模中断。为了致敬无线电时代， Cloudflare 的 CEO 就用“ 云闪爆发 ”（Cloudflare）命名了这种自己公司引发的网络中断现象。
Cloudflare 又是全球托管 React 应用最多的，被黑客自动化攻击的话后果不堪设想。 因此 Cloudflare 立即使用了专门针对重大 0 day 漏洞的全局配置系统下发更新，完全跳过常规发布流将最新 WAF 规则在最短时间内同步推送到全球所有数据中心。
