Lookup Failures for dual-stack domains in West Palm Beach/Miami

[mcd...@gmail.com]

Having some problems this morning with DNS for cd34.com (and a few other domains)

tsavo:Google mcd$ dig @8.8.8.8 cd34.com.

cd34.com has a wildcard subdomain which I thought might be related, but, a subdomain (secure.mywebsitecontrol.com) that publishes both an IPv6 and IPv4 address is also having the same problem. The main domain does report back correctly:

tsavo:Google mcd$ dig @8.8.8.8 secure.mywebsitecontrol.com

; <<>> DiG 9.7.3-P3 <<>> @8.8.8.8 secure.mywebsitecontrol.com

; (1 server found)

http://www.intodns.com/cd34.com reports everything as being fine - a few minor warnings but, only domains that have both IPv4 and IPv6 responses appear to be affected. I've checked a number of my domains that are dualstack, but, only a few appear to have a problem.

Using OpenDNS's resolvers, or, trying hostname lookups outside Miami appear to work fine - a VPS in Tennessee and a machine in Australia both report the correct information.

tsavo:Google mcd$ dig @208.67.222.222 cd34.com.

This was likely to be caused by some resolver issues we experienced today. This has been fixed now. Please check again.

Thanks,

Working fine now. Is there a status 'dashboard' or place to check resolver status?
