Support » Plugin: W3 Total Cache » CDN: sharp increase in download usage

  • Hi,

    Since I configured my CDN through W# Total Cache, I thought I could ask for some help here.

    I run an original PULL CDN through Amazon CLoudFront. It has been setup since August 2012. Works perfectly.

    Up until January my bill with Amazon CloudFront was constant. I do not host videos (always embedded YouTube but even that is rare).

    Since February of March, I’ve seen a significant increase in my Download Usage Report: it went from 10GB/month in January to 47GB/month for April.


    1) The number of HTTP request remains about the same: 150,000/month
    2) My traffic is constant, did not significantly increased or decreased. It’s also modest: between 250 and 500 visitors per day.

    The only “big” file I host on my blog are occasional 1 or 2MB PDFs.

    QUESTION: Well, I’m mostly looking for an explanation about what exactly could explain this behavior.

    Thanks a lot,
