While easy, uploading an entire directory with a s3 cp –recursive doesn’t feel like the most efficient approach, and definitely won’t scale well. With a static site, there are at least two reasons to be precise in operating on files. The first is that a clearing the cache at your CDN could have a performance impact if you experience a high volume of traffic. This is not currently an issue for us at Geotrocities HQ, but it’s certainly good to plan for the future.
