Our egress bill from Cloudfront last month, inc. the 1TB/per region free tier, was nearly $2,000. That's egress traffic ALONE (~20TB of it).
Needlessly to say, we're wrapping up testing on migrating our production (public) buckets to Cloudflare (R2) taking our cost from those $2,000 (and going up every month), to (drum roll)... $0,000/mo.
Have I mentioned AWS egress charges are borderline "extortionary"? :X
