This morning’s Cloudflare outage affected millions of websites across the globe.<\/h4>\n\n\n\n

If you\u2019ve ever tried loading your favorite website only to see an error message saying something like \u201cConnection timed out\u201d<\/em> or \u201cHost unreachable,\u201d<\/em> there\u2019s a good chance the problem wasn\u2019t your connection\u2014it was Cloudflare.<\/p>\n\n\n\n

Cloudflare<\/strong> is one of the most important companies on the internet, yet most people have never heard of it. And when Cloudflare goes down, huge parts of the web go with it.<\/p>\n\n\n\n

Let\u2019s break down what Cloudflare is<\/strong> and why outages make it feel like the entire internet is collapsing.<\/strong><\/p>\n\n\n\n

\n\n\n\n

What Is Cloudflare?<\/strong><\/h2>\n\n\n\n

Cloudflare is a global network that sits between websites and visitors. While many think of it as \u201cjust a CDN,\u201d it actually performs several mission-critical roles that keep the web fast, secure, and reliable.<\/p>\n\n\n\n

For businesses who care about performance and security (and they should<\/em>), Cloudflare\u2019s role is similar to what we talk about in our post on why strong cybersecurity is one of your best marketing tools<\/a>.<\/p>\n\n\n\n

Here\u2019s what Cloudflare does:<\/p>\n\n\n\n

1. Security & DDoS Protection<\/strong><\/h3>\n\n\n\n

Cloudflare shields websites from cyberattacks before they ever reach the server.
For many companies, this plays a major part in overall website safety\u2014right alongside fundamentals like maintaining an SSL certificate, which we cover here:

2. Content Delivery & Speed Optimization<\/strong><\/h3>\n\n\n\n

Cloudflare\u2019s global network of data centers delivers content from the closest location to the visitor, making sites load faster and reducing stress on your hosting.<\/p>\n\n\n\n

3. DNS (Domain Name System)<\/strong><\/h3>\n\n\n\n

Cloudflare runs one of the world\u2019s fastest DNS systems.
DNS translates human-friendly names\u2014like yourdomain.com<\/em>\u2014into server IP addresses.<\/p>\n\n\n\n

When Cloudflare\u2019s DNS has trouble, websites become unreachable even when the host is working fine.<\/p>\n\n\n\n

4. Reliability & Traffic Routing<\/strong><\/h3>\n\n\n\n

Cloudflare can keep a site online even if its server hiccups, thanks to caching, load balancing, and smart routing.<\/p>\n\n\n\n

Why the Internet Breaks When Cloudflare Goes Down<\/strong><\/h2>\n\n\n\n

Even brief Cloudflare outages can create huge ripple effects across the web. Here\u2019s why so many sites crash:<\/p>\n\n\n\n

1. Cloudflare Handles a Massive Portion of the Web<\/strong><\/h3>\n\n\n\n

Nearly 20% of the internet routes through Cloudflare.
