Package: dns-root-data Version: 2019052802 The C-Root is unreachable over IPv6 from some chunk of the Internet due to the ongoing (many-year) peering wars between Cogent and Hurricane Electric/Google. The website for the C root even describes the issue and suggests that there is no desire to address the issue (after all, the C root operator is a party to the dispute). This delays DNS requests for some users. It probably makes sense to patch out at least the v6 entry for the C Root.
