    How to prevent single point of failure without reg. new domain?


    Hello, what is the quickest way to setup DNS to prevent Single point of failure error (DNS in different geo location)?

    In my case hosting.com is hosted in USA and on this server are registered nameservers:
    ns1.hosting.com
    ns2.hosting.com

    both nameservers are pointed to one IP where is website hosting.com hosted. The DNS records on that webserver for ns1 and ns2 points to server with United Kingdom IP.

    Now when im having domain me.com , and using above mentioned nameservers, that is single point of failure

    Can i prevent this failure without registering new domain name? I already have a Linux VPS that is unused and can serve as a DNS. But im unsure if/how is the easiest and simplest way to setup that while i dont need to change me.com domain nameservers (this domain is set to these:
    ns1.hosting.com
    ns2.hosting.com)

    thank you

    That is not what I am seeing:

    ;; global options: +cmd
    ;; Got answer:

    So this is a reputable DNS service provider? If that is the case then I do not believe you have anything to worry about. They could be using anycast.
