Amazon CloudFront added cache tag invalidation that propagates in under 5 seconds, ending the choice between tracking individual URLs or nuking unrelated cached content with wildcards.
What: Amazon CloudFront launched invalidation by cache tag on April 29, 2026. Developers tag cached objects via HTTP response headers with comma-separated values, then invalidate all objects sharing a tag in one request. Invalidations propagate in under 5 seconds at P95 (under 25 seconds end-to-end). Available in all AWS Regions except China (Beijing and Ningxia). Each cache tag is priced as one path.
Why it matters: The focus on legal takedowns, compliance, and product updates reveals AWS optimizing for use cases where cache staleness is a correctness or liability issue, not just a performance tradeoff.
Takeaway: If you're using CloudFront, configure cache tag headers via the console/CLI/API, then tag objects in origin responses to invalidate product pages, compliance requests, or multi-tenant content with a single request.
