Our stack is: Fastly -> GTM (BBC CDN) -> Belfrage (BBC routing) -> origins for most of our modern web pages.
Currently, only Fastly supports Brotli, the others do gzip, deflate & no compression.
Fastly strips gzip,deflate from the accept-encoding header sent to origin so our layers all return uncompressed content which means they're using more egress bandwidth. It's not a huge problem for us but something I thought might be useful for others to know. #WebDev#Brotli#CDN#Compression#BBC
