Commercial transition
Previous stateBefore this change, Vercel had not applied this waiver to CDN Requests and Fast Data Transfer generated by traffic that WAF denied, challenged or rate-limited.
→New stateCDN Requests and Fast Data Transfer are waived for traffic denied, challenged or rate-limited by Vercel WAF.
Who is affected
Projects using Vercel Firewall rules that deny, challenge or rate-limit traffic.
Action required
No configuration is required; the waiver applies automatically. Teams can update CDN cost forecasts because mitigated traffic no longer incurs the waived CDN Requests and Fast Data Transfer charges.
Evidence boundary
The official changelog establishes the automatic waiver for CDN Requests and Fast Data Transfer when Vercel WAF denies, challenges or rate-limits traffic. It does not make allowed traffic or unrelated CDN charges free.
