On parts of the website like
- User avatars (aeiljuispo.cloudimg.io)
- api-inference.huggingface.co
- Subdomains on hf.space
are not reachable using IPv6, despite CloudFront and AWS supporting IPv6 for some time already.
(I don’t know about the internals, especially not about the servers where the models run and fetch their traning data from, but if they do not support it either it might be a good idea to also roll it out there, if possible.)
As IPv6 is the modern internet protocol it would be a good idea to fully support it.
