: DNS configuration on website makes it available only some of the time The DNS configuration on my website is periodically dropping visitors and I have no idea why. Most of my website's visitors

@Hamaas447

I've found the problem and fixed it - The nameservers was configured in my server to my 2 IPs, and on the registrar I've configured them in the opposite order to what configured in the server.
Thanks for the answers - I would vote up but I cannot do it because I just found out that part of StackExchange.. sorry

I have double checked with intoDNS and it is fine also www.intodns.com/2mp3.co.il
Are you saying that bot NS are on the same server ? (this is dangerous, single point of failure)

What is the error they are seeing ? Can you ask someone to ping your server when it is happening ? Do you have any packet loss when you ping your server for a while ?

I recommend either using your hosting company's nameservers or setting up one on a service dedicated to this. (I have used worldwidedns.net for years and recommend them, it's per year for a single domain and they give you complete control over your DNS.)

It's not a good idea to burden your web server machine with nameserver duties as well, if that is what you're doing.

No host records exist for ns1.hosty.co.il and ns2.hosty.co.il. No wonder the clients have problem resolving 2mp3.co.il if the authoritative name servers doesn't even exist?!
