CDN info

trying to ensure things aren't lost in the matrix chat, so we keep things here for historical record :slightly_smiling_face:

* Apparently Cloudflare doesn't do media asset caching by default ([src](https://podverse.fm/clip/g9uwYUqn-) - @StefanS-O)
* bunny.net is supposed to be pretty cheap ([src](https://matrix.to/#/!rDlEtonuSythLzmxQL:jupiterbroadcasting.com/$K2cuul5BalVOcsXAMVSQrA1hEa1dQmFbyD_JSwyRV-8)):
> I been using them for a little less than a year now and use about a quarter of a TB in bandwidth with them a month. My bill has never been over 3USD a month.
* maybe a backblaze + Cloudflare integration ([src](https://matrix.to/#/!rDlEtonuSythLzmxQL:jupiterbroadcasting.com/$fwNqNmTr-rT6-tPzMhjX5wnjn4t_473QCmyvIfbWJoE)):
> Backblaze's cloud offering has some peering deal with CloudFlare that results in you getting the cloudflare CDN for free in front of your backblaze object storage.
* @ChrisLAS has mentioned using R2 before, but not directly a CDN (I think this is because they have free egress (IIRC))
* #167 has been mentioned
