    Hi,

    I'm in London and since the issues a while ago with the London openDNS servers (which I understand have been fixed), I still seem to be accessing the Amsterdam servers.

    Dig output:

    >dig @208.67.222.222 txt which.opendns.com +noall +short
    "5.ams"

    >dig @208.67.220.220 txt which.opendns.com +noall +short
    "7.ams"

    Traceroute:

    >traceroute 208.67.222.222
    traceroute to 208.67.222.222 (208.67.222.222), 30 hops max, 40 byte packets

    Anybody know why?

    Thanks,

    Because Virginmedia and Level-3 have configured suboptimal routing for the OpenDNS anycast addresses, as seen from your traceroute.
    Best is to open a support ticket, so that OpenDNS can work with ISPs and network carriers to get this fixed.
