Vercel Functions Creation Errors Hit Singapore Data Center

What happened

Major CDN and hosting providers experienced a series of service disruptions between March 24-25 and April 19-21. Vercel reported multiple incidents including elevated dashboard errors, API endpoint failures, and inaccessible runtime logs that affected deployment visibility. Akamai's Certificate Provisioning System (CPS) experienced issues on March 24, though the company later determined there was no actual customer impact. Cloudflare users faced problems with challenge verification systems on April 20, preventing some visitors from accessing protected sites. Akamai also reported edge delivery problems in their Frankfurt data center that required service fixes.

Business impact

Dashboard and API failures can prevent teams from monitoring deployments during critical release windows, creating blind spots in production systems. Certificate provisioning issues, even false alarms, highlight the dependency risks that can halt HTTPS-dependent e-commerce operations. Challenge verification failures directly block legitimate users from accessing websites, immediately impacting conversion rates and user experience metrics.

Background

These incidents illustrate the concentrated risk in modern web infrastructure, where a handful of CDN and edge computing providers serve the majority of enterprise websites. Vercel has become a dominant platform for modern web applications, particularly for teams using Next.js and similar frameworks. The clustering of issues across multiple providers within a similar timeframe raises questions about shared infrastructure dependencies or coordinated maintenance windows that weren't properly communicated.

What this means for your team

Implement monitoring that tracks both your application performance and your hosting provider's status pages during deployment windows. Set up alternative deployment pipelines or rollback procedures that don't rely solely on provider dashboards, especially for time-sensitive releases. Establish clear escalation procedures when provider status pages conflict with observed behavior, as demonstrated by Akamai's initial CPS alert. Document dependencies on third-party challenge systems and test fallback authentication methods to prevent user lockouts during CDN issues.

What to watch

Monitor whether these providers publish post-incident reports that reveal shared infrastructure causes or coordination gaps. Track if similar multi-provider incident patterns emerge, which could indicate broader edge computing infrastructure vulnerabilities.
