Cannot reach f.root-server.net and c.root-servers.net over IPv6
I've never been able to reach c.root-servers.net over IPv6 and since April 16, 2017, I have not been able to reach f.root-servers.net over IPv6. "Reach" means receiving an answer to a DNS query for the root zone SOA resource record set. My logs, for f-root, showing when it went from "good to bad". The numbers after SOA, TCP and UDP are the number of bytes received asking for the SOA RR over TCP, and then the root DNSKEY set over TCP and then UDP. The lines show the IPv6 address used for F. third-sizes-2017-04-10-120000-2-combo:zone . f.root-servers.net. 2001:500:2f::f GOOD v6 SOA 857 TCP 1139 UDP 1139 third-sizes-2017-04-11-120001-2-combo:zone . f.root-servers.net. 2001:500:2f::f GOOD v6 SOA 857 TCP 1139 UDP 1139 third-sizes-2017-04-12-120001-2-combo:zone . f.root-servers.net. 2001:500:2f::f GOOD v6 SOA 857 TCP 864 UDP 864 third-sizes-2017-04-13-120001-2-combo:zone . f.root-servers.net. 2001:500:2f::f GOOD v6 SOA 857 TCP 864 UDP 864 third-sizes-2017-04-14-120001-2-combo:zone . f.root-servers.net. 2001:500:2f::f GOOD v6 SOA 857 TCP 864 UDP 864 third-sizes-2017-04-15-120001-2-combo:zone . f.root-servers.net. 2001:500:2f::f GOOD v6 SOA 857 TCP 864 UDP 864 third-sizes-2017-04-16-120000-2-combo:zone . f.root-servers.net. 2001:500:2f::f GOOD v6 SOA 857 TCP 864 UDP 864 third-sizes-2017-04-17-120001-2-combo:zone . f.root-servers.net. 2001:500:2f::f BAD v6 SOA missing TCP missing UDP missing third-sizes-2017-04-18-120001-2-combo:zone . f.root-servers.net. 2001:500:2f::f BAD v6 SOA missing TCP missing UDP missing third-sizes-2017-04-19-120000-2-combo:zone . f.root-servers.net. 2001:500:2f::f BAD v6 SOA missing TCP missing UDP missing For C, the address I use is 2001:500:2::c, I've never gotten a response from there.
