Cloudflare Outage: Should You Go Multi-CDN?
None
<p><span style="font-weight: 400;">As a DDoS testing and resilience consultancy, we routinely advise our clients to strengthen their architecture by using a reputable CDN like Cloudflare. After this week’s Cloudflare outage, however, many organizations are understandably asking themselves a new question:</span><span style="font-weight: 400;"><br> </span><span style="font-weight: 400;">Should we adopt a multi-CDN strategy instead of relying on a single provider?</span></p><p><span style="font-weight: 400;">For the </span><i><span style="font-weight: 400;">vast majority</span></i><span style="font-weight: 400;"> of businesses, the answer is </span><b>no</b><span style="font-weight: 400;">.</span></p><p><span style="font-weight: 400;">Whether you build a strategy around a dedicated multi-CDN platform or combine multiple providers yourself—Cloudflare, Akamai, Amazon CloudFront, Azure CDN, and others—the operational drawbacks usually outweigh the benefits.</span></p><p><span style="font-weight: 400;">Events like the Cloudflare outage are rare, and when they occur, they affect a huge portion of the Internet. A multi-CDN setup can, in theory, improve availability. But the real-world cost is substantial:</span></p><ul> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Higher architectural and operational complexity</span><span style="font-weight: 400;"><br> </span></li> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">Difficult integration and configuration</span><span style="font-weight: 400;"><br> </span></li> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">More points of failure</span><span style="font-weight: 400;"><br> </span></li> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">If both CDNs are active, then double the monitoring and ongoing maintenance, and the attack surface increases. </span></li> <li style="font-weight: 400;" aria-level="1"><span style="font-weight: 400;">If one CDN is active and the other is dormant, then activating the latter is risky for security concerns and other business risk.</span><span style="font-weight: 400;"><br> </span></li> </ul><p><span style="font-weight: 400;">For most organizations, a well-engineered single-CDN deployment, complemented by regular <a href="https://www.red-button.net/ddostesting/" rel="noopener">independent DDoS testing</a>, delivers stronger resilience and far better manageability.</span></p><p><span style="font-weight: 400;">A multi-CDN approach only truly makes sense for a narrow group of companies with massive global audiences, extreme traffic volumes, and strict availability requirements—typically large streaming platforms, gaming companies, and media-heavy services.</span></p><div class="spu-placeholder" style="display:none"></div><div class="addtoany_share_save_container addtoany_content addtoany_content_bottom"><div class="a2a_kit a2a_kit_size_20 addtoany_list" data-a2a-url="https://securityboulevard.com/2025/11/cloudflare-outage-should-you-go-multi-cdn/" data-a2a-title="Cloudflare Outage: Should You Go Multi-CDN?"><a class="a2a_button_twitter" href="https://www.addtoany.com/add_to/twitter?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fcloudflare-outage-should-you-go-multi-cdn%2F&linkname=Cloudflare%20Outage%3A%20Should%20You%20Go%20Multi-CDN%3F" title="Twitter" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_linkedin" href="https://www.addtoany.com/add_to/linkedin?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fcloudflare-outage-should-you-go-multi-cdn%2F&linkname=Cloudflare%20Outage%3A%20Should%20You%20Go%20Multi-CDN%3F" title="LinkedIn" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_facebook" href="https://www.addtoany.com/add_to/facebook?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fcloudflare-outage-should-you-go-multi-cdn%2F&linkname=Cloudflare%20Outage%3A%20Should%20You%20Go%20Multi-CDN%3F" title="Facebook" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_reddit" href="https://www.addtoany.com/add_to/reddit?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fcloudflare-outage-should-you-go-multi-cdn%2F&linkname=Cloudflare%20Outage%3A%20Should%20You%20Go%20Multi-CDN%3F" title="Reddit" rel="nofollow noopener" target="_blank"></a><a class="a2a_button_email" href="https://www.addtoany.com/add_to/email?linkurl=https%3A%2F%2Fsecurityboulevard.com%2F2025%2F11%2Fcloudflare-outage-should-you-go-multi-cdn%2F&linkname=Cloudflare%20Outage%3A%20Should%20You%20Go%20Multi-CDN%3F" title="Email" rel="nofollow noopener" target="_blank"></a><a class="a2a_dd addtoany_share_save addtoany_share" href="https://www.addtoany.com/share"></a></div></div><p class="syndicated-attribution">*** This is a Security Bloggers Network syndicated blog from <a href="https://www.red-button.net/">Red Button</a> authored by <a href="https://securityboulevard.com/author/0/" title="Read other posts by Ziv Gadot">Ziv Gadot</a>.
