I do observe two potential problems, however: - For the past 24-48 hours, there seem to be some significant routing problems on the IPv4 internet, resulting in people using various diverse ISPs (including myself at home) being unable to route to any of my servers. This issue doesn't affect IPv6, however. - The DNS seeder seems to only be responding to requests received over IPv4. This means IPv6 DNS servers get no response. :( Luke
