Bug ID: 45612 Summary: Enable IPv6 for dl.winehq.org Product: WineHQ.org Version: unspecified Hardware: x86 OS: Windows Status: UNCONFIRMED Severity: normal Priority: P2 Component: www-unknown Assignee: wine-bugs@winehq.org Reporter: raul.tambre@gmail.com
dl.winehq.org uses Fastly. Per Fastly's IPv6 documentation (https://docs.fastly.com/guides/basic-setup/ipv6-support.html), it's as easy as changing the CNAME on dl.winehq.org from k.global-ssl.fastly.net to dualstack.k.shared.global.fastly.net. I tested manually with curl and it works.
Making the switch would also enable HTTP/2.
