 * OK, thanks for helping narrow down the cause – though I’m not convinced its an
   invalidation problem because we haven’t uploaded any new attachments, nor updated
   any plugins, nor manually purged the CDN, and as mentioned the charges are S3
   request-tier1, which is PUT, COPY, POST, and LIST requests to the S3 bucket not
   invalidations on CloudFront – as far as I understand it… I’m obviously not a 
   guru on such things, things 😉
 * Appreciate your time & suggestions.

 * Hi Marko –
 * Correct: W3 Total Cache w/ CDN active using “Amazon CloudFront Over S3”. We are
   no longer using any other offload plugin. I just mentioned that as reference /
   comparison base for the big increase in S3 cost due to millions of Request-Tier1
   requests from S3 once we did activate the CDN option in W3 total cache. Sites
   that get very little traffic are getting 250,000+ S3 requests per day from the
   W3 Total Cache plugin when nothing is being uploaded or changed on the website.
 * Since that Request-Tier1 type includes LIST (as well as PUT, COPY, & POST), we
   thought we had narrowed it down to being a result of the “Export changed files
   automatically” option making thousands of LIST requests a day to compare files
   and/or the issue that seems to remain that max-age and expiration headers aren’t
   being passed when the CDN is set to “Amazon CloudFront Over S3”, but shutting
   that option off didn’t solve it, unfortunately. (even though LIST still “feels”
   like it’s the cause since we’re definitely not adding any new attachments or 
   files yet getting the huge numbers on S3)
 * It’s the same issue as the other post I referenced in the first post that was
   closed due to no new replies and hoping there’s been a solution / recommendation
   since then (other than deactivating the CDN option).
 * Thanks for your time. Much appreciated.
