　　Bad effects of shielding DNS

China Telecom has briefly shielded the server address GoDaddy, but that for the users in GoDaddy to buy the site is not small, this direct shielding the NS (domain name resolution) service, the impact is very bad, in order to "punish" a certain one or two sites, The direct result of thousands of innocent sites can not be visited, is described as "rather wrong kill 1000, not let one" extreme means.

I am here to confirm that the GoDaddy DNS server has 57, 58, 67, 68, 77, 78, 33, 34th, if your domain name uses these several DNS addresses, you need to modify it to another DNS address, otherwise you will not be able to access from some areas.
