Adrian, I don't think it's appropriate or constructive on this list to ask someone to fix their name servers. This seems to be beyond the scope of the WG's charter. You would be better to take up the problem of the broken servers directly with those responsible for that delegation. Contact details are in the NCC's whois database. IMO, the enum-wg list shouldn't be for discussing current operational problems, notifications of outages and so on. However I do think it would be the right place to discuss monitoring and trouble reporting procedures. For example, perhaps the WG could recommend that ENUM delegations provide "standard" email addresses are provided for reaching the tech/zone/admin contacts and/or trouble reporting systems. eg: {tech-c,zone-c,admin-c,trouble}@<CC>.e164.arpa or something like that.
