Im not really that knowledgeable in servers and set-ups, but have my own dedicated server that runs my business website.
Currently both name servers of my domain are the same server, which I intent to change, because if the current NS goes down, my website becomes unreachable.
Am I right about having more NS' from different people, the less chance my website will be unreachable?
And also the A record for my domain points to my servers IP address which is all good and works apart from when the hoovering needs to be done then i get unplugged and go down. so what i'm after is updating the domain and adding anther A record so if my server gets unplugged or goes down the back up server will kick in at a different place or address.
Am I correct in saying that I can add more name servers from different companies and more A records that points to different servers?
