The nameservers 41.213.123.[39,40] are timing out queries from us. Please ask the nameserver owner to unblock Google Public DNS: https://developers.google.com/speed/public-dns/faq#locations

Hi 

Please assist: Using Google's public dns my domain name: zadeveloper.com (in fact all domains on my dns server) are unable to resolve. However using zonecheck or mx toolbox it resolves correctly.

You confirmed that your nameserver can reach Google Public DNS. However, that does not mean the opposite route works. When I try a query from our resolvers to these two nameservers, it still times out. Could you check if your nameservers have received queries from Google Public DNS? If not, they may be dropped in another part of your network.

Dear Concerns,
Please elaborate times out is it reffering to ICMP timeout or lookup timeout?

Thanks
F.

It's DNS query timeout.

Hello Jarrod,
Non of the Public DNS servers are resolving your domain. Seems issue is that your DNS is not allowing queries as mentioned by Mr.Shen. Please contact your DNS admin


Thanks
F.
