I have domain CNAMEd to www.cloudflare-ipfs.com with dns link record
CNAME www www.cloudflare-ipfs.com Auto DNS only
TXT _dnslink.www dnslink=/ipns/filecoin.io/ Auto DNS only
I am using filecoin.io content for testing before uploading mine to IPFS.
Problem is that some servers in cloudflare-ipfs.com cluster ignore dnslink record and they are trying to serve domain as IPNS and return 404 error with message
ipfs resolve -r /ipns/www.domain.com/resources/: could not resolve name
You need to do page reload until it hits correct server. It also happens for images so most of images are broken. This means that offered IPFS gateway service is pretty unreliable service and not good for production use.
