Does anyone know which (if any) CDNs support zstd compression?
Apparently it's used for at least one response within ~13% of pageviews [1], so I'm guessing that's Meta's web properties (given it's their tech), one big CDN or some other third-parties 🤔

@ryantownsend @programmingart my guess is the usage is a combination of Meta's web properties and their 3rd-party embeds on other sites (retargeting js).
To trigger the feature usage it just needs to be used by one response anywhere in the page.
I know there's one other big Asian site that uses it but can't remember which off the top of my head.
@orangeacme @PatMeenan @programmingart I haven’t personally implemented it, but it compresses far faster than Brotli at similar rates of compression.
Should be pretty beneficial for large CDNs cost-wise over compressing with Brotli, which is why many only compress cacheable content.
Zstd should make on-the-fly compression possible while having a better compression ratio than Gzip.
