Quic is being standardized in the IETF there are a couple of companies involved:
- Cloudflare
- Facebook: They already use QUIC for some of their products, or at least it's a pretty sensitive piece of software on their architecture because they ask to report bugs to the bug bounty program[1]
- Microsoft
- Nginx
- Google
- NetApp
- Mozilla
- Traffic Server
- Litespeed
- Fastly
- F5
- Apple
Amazon is very quiet about all that, but they are probably looking into it. So, it is pretty backed up. If you take a look at their workgroup homepage (quicwg.org) you will see a couple of open source implementations, some from those same companies.
