Panic spreads when users try to access a website and it doesn\u2019t work\u2014instead of the usual content, the screen just shows a 502 Bad Gateway error. Why does this happen? Do you know what Cloudflare is and what it does? Here\u2019s the answer.<\/strong><\/p>\n\n\n\n<p>There are many reasons why the internet might not work properly, but if you see a <strong>502 error<\/strong> in your browser, don\u2019t worry\u2014it\u2019s not your fault. The only ones responsible for that outage are <strong>companies like the one we\u2019re talking about today: Cloudflare<\/strong>.<\/p>\n\n\n\n<p>A 502 means the <strong>failure happened at a CDN company<\/strong>. But let\u2019s start from the beginning: The internet works by connecting computers to each other, so if you want to access a website on a specific server, only those close to that server will have good access and high speed.<\/p>\n\n\n\n<p>That\u2019s why <strong>networks of servers around the world store and replicate websites<\/strong>, apps, and data so everyone can access them quickly and with similar quality.<\/p>\n\n\n\n<p>These are called CDNs, and they\u2019ve become a key part of the internet and services like streaming platforms or social networks, which we want to access from anywhere, anytime, <strong>without suffering from high latency<\/strong>.<\/p>\n\n\n\n<p>Cloudflare was founded in 2009 with this concept, but over the years, this company and others have gone further. Besides <strong>offering an optimal content distribution network<\/strong>, Cloudflare also aims to <strong>protect us from cyberattacks<\/strong>.<\/p>\n\n\n\n<p>Companies using Cloudflare servers to be online\u2014like Dropbox or Pinterest\u2014also get <strong>cybersecurity protection against DDoS attacks<\/strong>.<\/p>\n\n\n\n<p>The <strong>1.1.1.1 DNS service<\/strong>, which promises to respect user privacy, and the <strong>Warp VPN<\/strong> are some of the tools Cloudflare has created, making its service more secure than other CDNs.<\/p>\n\n\n\n<p>By acting as intermediaries between client and server with <strong>reverse proxies<\/strong>, they can detect malicious traffic and limit spam. However, sometimes problems arise.<\/p>\n\n\n\n<p>It\u2019s not often, but the infrastructure can fail, and that\u2019s when the famous 502 appears and websites depending on those CDNs stop working. Just a month ago, we witnessed and suffered one of these issues, <strong>blocking millions of websites<\/strong>.<\/p>\n\n\n\n<p>There\u2019s nothing we can do but wait for them to fix it. <strong>Be patient and check these companies\u2019 social media<\/strong> for updates on such problems.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Sometimes we have to report that the internet is down.
