Cloudflare Global Datacenter Maintenance Wave May 11-14 2026

What happened

Cloudflare is executing a coordinated wave of scheduled maintenance across eight major datacenters between May 11-14, 2026. The maintenance windows affect key locations including London (LHR), Los Angeles (LAX), Sydney (SYD), Amsterdam (AMS), Osaka (KIX), St. Louis (STL), Colombo (CMB), and Córdoba (COR). Maintenance in St. Louis and Colombo has already completed, while Amsterdam operations are currently in progress. Cloudflare warned that traffic will be re-routed from affected locations during maintenance windows, potentially causing slight latency increases. The remaining scheduled maintenance includes Los Angeles (May 13, 09:00-11:00 UTC), Córdoba (May 13, 13:00-16:30 UTC), and Sydney (May 14, 15:00-21:00 UTC).

Business impact

Enterprise websites using Cloudflare CDN services may experience increased page load times during maintenance windows, particularly for users geographically closest to affected datacenters. E-commerce sites could see conversion rate impacts if checkout flows or product pages load slowly during peak regional traffic periods.

Background

Coordinated maintenance across multiple Cloudflare datacenters is relatively uncommon and suggests significant infrastructure upgrades. Cloudflare's CDN serves millions of websites globally, making any service degradation potentially widespread. The timing across different regions indicates planned infrastructure improvements rather than emergency maintenance.

What this means for your team

Monitor website performance metrics closely during remaining maintenance windows, especially for traffic originating from Los Angeles, Argentina, and Australia regions. Configure additional performance monitoring for critical user journeys during the May 13-14 maintenance windows. Consider temporarily adjusting marketing campaigns or promotional activities that drive traffic to regions under maintenance to minimize revenue impact from potential latency increases.

What to watch

Monitor Cloudflare status updates for any extensions to the remaining Los Angeles, Córdoba, and Sydney maintenance windows. Watch for reports of extended latency or connection issues from users in affected regions during the scheduled timeframes.
