内容总结：

今日上午，全球多地互联网用户遭遇网站访问故障。经查，此次大规模服务中断源于知名网络服务提供商Cloudflare的全球性系统故障。

受影响的网站范围广泛，包括社交媒体平台X及故障监测网站Downdetector等。用户访问时普遍出现“内部服务错误”或“请解除对challenges.cloudflare.com的屏蔽”等提示。由于Cloudflare为全球众多网站提供网络基础设施和网络安全服务，其系统故障引发了连锁反应，导致依赖其服务的网站集体“瘫痪”。

据技术媒体Techradar报道，Cloudflare原定于UTC时间11月18日12时至15时（美国东部时间7时至10时）进行系统维护，此次故障可能与此前计划的维护工作有关。这已是近期第二次重大网络中断事件，上月亚马逊云服务（AWS）也曾出现类似故障，暴露出互联网服务过度集中化带来的系统性风险。

目前Cloudflare正在紧急修复系统，预计今日将逐步恢复服务。本报将持续关注事件进展。

中文翻译：

今晨若您访问各类网站及在线服务时遇到障碍，这并非个例：全球内容分发网络服务商Cloudflare似乎正遭遇大面积服务中断。

当我尝试加载X（原推特）或颇具讽刺意味的故障监测网站Downdetector时，屏幕上不断弹出各类报错信息。X平台显示"内部服务错误"，而Downdetector则要求"请解除对challenges.cloudflare.com的屏蔽以继续访问"（显然我并无此权限）。今晨您尝试访问的任何网站都可能出现类似问题，即便是平日不曾浏览的站点也不例外。例如在撰写本文过程中，我通过谷歌搜索并点击从未听闻的网站链接时，遭遇的同样是这类报错提示。

这种现象源于全球大量网络服务对Cloudflare的深度依赖。该企业为众多公司提供网页基础设施与网络安全产品等系列服务。正因如此，当Cloudflare服务崩溃时，大量网站便如多米诺骨牌般接连瘫痪。

目前尚不确定导致本次服务中断的具体原因。但据Techradar报道，Cloudflare原定于世界标准时间11月18日12:00至15:00（美国东部时间7:00至10:00）对部分网络服务器进行计划内维护，很可能在维护过程中出现了意外故障。

尽管这确实造成了严重的网络中断，但类似事件早已屡见不鲜。上月亚马逊云服务AWS的故障就曾导致全球网络瘫痪。本次Cloudflare事件再次警示我们：当众多企业将网络服务需求集中于少数供应商时，一旦某家服务商出现故障，整个互联网生态都将遭受剧烈冲击。

Cloudflare很可能在周二内修复该故障，相信各项服务不久便会恢复正常。本文将持续关注事件进展并及时更新动态。

If you're having trouble accessing sites and services on the internet this morning, it isn't just you: It appears Cloudflare is experiencing a global outage.
When I try to load sites like X or, ironically, Downdetector, I'm met with various errors. X shows me an internal service error, while Downdetector asks me to "Please unblock challenges.cloudflare.com to proceed." (I definitely do not have that authority.) You may experience similar errors on websites you try to load this morning, even ones you don't regularly visit. As part of this article, for example, I would google queries and click the top results to websites I had never heard of before, only to encounter similar error messages.
That's because a large portion of the global internet relies on Cloudflare to operate. Cloudflare offers a host of services to companies, including web infrastructure and cybersecurity products. As such, when Cloudflare goes down, so do many of those websites—a bit of a domino effect.
It's not clear at this time what brought on the outage, but, as spotted by Techradar, Cloudflare had announced scheduled maintenance for some of its web servers for Nov. 18, ranging from 12 p.m. to 3 p.m. UTC (7am to 10am ET), so it's possible something happened during this work to break service.
While this is indeed a big interruption to the internet, it's far from the first time this has happened. In fact, an AWS (Amazon Web Services) outage broke the internet last month. With the Cloudflare outage this morning, it's an example of the risks of so many companies putting their web services needs in the same basket: If one servicer goes, so too goes a huge fraction of the web.
Cloudflare will likely patch this issue sometime Tuesday, so I imagine we'll all be back to business as usual soon enough. I'll keep this article updated with developments as they come.
