CDN Bandwidth usage

Hi community,

Mid-October, we've witnessed a sudden increase in CDN usage on our repo, and we're not sure why that is, could you help us figure it out?

  • Our API endpoint has been updated from to on September 27
    • You can see a spike on the graph below, most likely related to this change
    • Do you know why?
  • Since Oct 9, our usage has been extremely high, whilst our Netlify usage has gone down (static website)
  • In the October/November period, we've even reached 186% of bandwidth usage (never done before)


Hi Thomas,

From my experience, this is usually related to a video, did you upload any videos around mid october?

I should warn: serving videos from the Media Library can very quickly eat up your bandwidth allowance. You might want to consider a dedicated video hosting service, like YouTube, Vimeo, or Wistia. If you do choose to host your videos on Prismic, keep a close eye on your bandwidth usage.


Hi Phil,

Thanks for the answer. We did start to use a video on our home page around that date. We'll switch to Wistia, and follow up here if bandwidth doesn't go down.

Hi again, @Phil

Just to let you know that we did move our video to Wistia, and it looks like problem solved.

Thanks for the help!
