Mitigating DDoS AttacksĭDoS attacks are hard to mitigate because they come from many different IP addresses and often from legitimate but compromised computers. This set of infected machines is called a botnet: tens of thousands of devices from personal computers to compromised servers sending traffic to the target website simultaneously, effectively overloading it and making it inaccessible to legitimate users. In a distributed denial-of-service attack, these requests come from many different IP addresses, typically belonging to malware-infected devices (including ‘smart’ home appliances like refrigerators!). DDoS attacks can target a specific site, IP address, or an entire hosting platform.Ī typical denial-of-service attack involves a malicious actor sending a massive number of HTTP requests (or TCP packets) to your website 1 - typically several orders of magnitude more than usual, exhausting its resources and preventing it from serving legitimate traffic. Attacks are often orchestrated by malicious actors motivated by profit or politics or just a desire to cause general chaos. These requests aren’t legitimate traffic trying to access your website or API in the way you intend. DDoS attacks flood a site with requests from multiple IP addresses simultaneously. DDoS Attacks ExplainedĭDoS stands for Distributed Denial of Service. By eliminating DDoS as a threat, we help ensure your users have uninterrupted access to your content and services at all times. When you entrust Render to replace your DevOps team, you rely on us to keep your site available, even when it’s under attack. It’s one of the most important features we can offer to you. And while it may not be the brightest, shiniest feature, reliability is always top of mind for our work at Render. These attacks are a threat to your site’s uptime and responsiveness and are typically complex and time-consuming to diagnose and resolve. Why do we care about DDoS protection?Īs DDoS attacks continue to increase in size and frequency, we don’t want Render users to have to worry about them.

See our community post detailing Render’s response for details. Even better, we made this change with no downtime, which is exactly how we like to launch significant infrastructure improvements to Render!Īn additional (and timely) benefit to Render users is Cloudflare’s quick work to mitigate the log4j vulnerability announced last week. Since releasing this feature, we’ve protected customers from more than one thousand DDoS attacks.

We’re using Cloudflare’s industry-leading DDoS protection infrastructure behind the scenes. A few months ago, Render quietly became the first full-stack Platform-as-a-Service to offer completely free DDoS protection to every application and website hosted on our platform.
