Introduced rate limits on recursive/nested Edge Functions calls within your project. Rate limiting applies to outbound fetch() calls made by Edge Functions to other Edge Functions, including direct recursion, function chaining, circular calls, and fan-out patterns.
Rate limit budget: Each request chain has a minimum budget of 5,000 requests per minute. Inbound requests and external API calls are not affected.
Why introduced: Recursive function calls were causing increased response times across multiple regions. Based on metrics, the rate limit affects only 0.4% of projects. A guide on avoiding rate limits is available in the docs.
