AGAIN, BBX-DNS problem has recurred.

$ dig ns bbx.2ch.net
>> no reply.

Unless it fixies this completely, Rock54 ability cannot be demonstrated.

Can't again and such a thing be prevented from whether already happening?

bbx.2ch.net. 259200 IN NS a.ns.bbx.2ch.net.
a.ns.bbx.2ch.net. 259200 IN A 206.223.151.207

Please, it would like to complete this.
