The next time a game loads suspiciously fast, thank the invisible CDN. And that CDN is often a subdomain ending with .cloudfront.net . Have you encountered a suspicious cloudfront.net link while gaming? Report it to AWS abuse (abuse@amazonaws.com) along with the full URL. Help keep the gaming community safe.

For the average user, seeing d3c1abc123.cloudfront.net in their address bar or download manager can be confusing—and sometimes alarming. Is it a virus? A scam? A peer-to-peer sharing site?

Create a CloudFront distribution pointing to that S3 bucket. Choose edge locations (all is fine).

However, always remain vigilant. Only download from cloudfront.net if they come from an official game launcher or a trusted developer’s website. For everything else—images, videos, audio, 3D models—you can rest easy knowing that cloudfront.net is just the internet’s fastest delivery truck for your favorite games.

Upload your game files (HTML, JS, WASM, assets) to an S3 bucket.

Attach a custom domain (optional but recommended). Instead of mygame.cloudfront.net , you can use cdn.mygame.com via a CNAME record.

Test using curl or a browser. Your game will now load globally with sub-100ms latency.

(Important) Configure cache behaviors. For game assets, set a long TTL (time-to-live) – e.g., 30 days. For your main index.html , set a short TTL (e.g., 5 minutes) so updates propagate quickly.
