    # XXX
    # We've been having issues with bogus DNSSEC responses, and unintended
    # blacklisting of nameservers because of that.
    # The following is intended as a stopgap solution.
    #
    # unbound had issues with auro.re's DS records, apparently;
    # it kept receiving an error, which subsequently caused a blacklisting
    # of relevant servers and an inability to resolve auro.re and its
    # subdomains.
    #
    # auro.re does not have DNSSEC anyway, so we can treat it as insecure.
