A few weeks ago I used AWS S3 for 301 redirects, with Cloudflare on top to cache these requests, few as they were. This effectively maintains a handful of links which redirect somewhere useful, while directing all other traffic to this domain.

The results are great! The switch to S3 was made on the 9th, and a Cloudflare page rule added on the 10th – at which point over 60% of requests became cached.
The page rule I added was:
- URL: domain.com/*
- Cache Level: Cache Everything
- Edge Cache TTL: a month

Crucially, I no longer have a server to manage, and the AWS cost for all hits to this S3 bucket is currently at a grand total of $0.00.
