DefiLlama has resolved an issue that caused intermittent 403 errors affecting approximately 2.9% of its API requests, including 0.8% of paid API requests. The company announced that the problem, which has now been fixed, was due to recent adjustments in Cloudflare's CDN behavior, leading to some regions and specific interfaces intermittently returning a "error 1000" 403 error. DefiLlama has committed to providing refunds to users impacted by this disruption.
