Major CDN Outages Hit Netlify, Vercel, Cloudflare in Early May

What happened

Three major content delivery and hosting platforms experienced significant service disruptions between May 6-8, 2024. Netlify reported elevated errors and latency affecting their global network on May 6, followed by IAD region-specific issues on May 8 due to upstream AWS problems. Vercel experienced dashboard errors on April 21 and deployment failures on May 7, with their IAD1 region seeing widespread service impacts on May 8. Cloudflare faced network connectivity issues in their Tokyo data center on May 7, while conducting scheduled maintenance in Bucharest and Montreal.

Business impact

Enterprise teams using these platforms for production hosting, CI/CD pipelines, or edge delivery faced deployment delays and potential site accessibility issues. Organizations with single-vendor dependencies likely experienced cascading failures affecting release schedules and user experience. The concentration of incidents in the IAD (Washington DC) region particularly impacted North American operations.

Background

These platforms collectively serve millions of websites and are critical infrastructure for modern web operations, especially for teams using JAMstack architectures and automated deployment workflows. The AWS dependency revealed by Netlify's IAD incident highlights how cloud infrastructure interconnections can amplify regional outages. Enterprise teams increasingly rely on these services for both development workflows and production traffic distribution.

What this means for your team

Implement multi-CDN strategies using providers with different upstream dependencies to avoid correlated failures. Establish monitoring for both your applications and the status pages of critical third-party services, with automated alerting for incidents affecting your regions. Review your deployment rollback procedures and ensure you can quickly switch traffic between providers during extended outages. Document which services depend on each platform to accelerate incident response.

What to watch

Monitor whether these platforms publish post-incident reviews with technical details about the root causes and prevention measures. Track any changes to their SLA terms or incident communication procedures following this cluster of outages.
