I was using S3 to deliver secure signed downloads to customers. It worked well enough for a long time but eventually customers started having major connectivity issues and dead slow downloads. I switched to CliudFront and, of course, downloads improved dramatically. I had to go with CF because we needed signed downloads. Would be nice to have alternatives but I'm happy with CF.
