I have the following dns servers:
root@core [~]# cat /etc/resolv.conf
nameserver 209.51.143.76
nameserver 209.51.128.19
nameserver 209.51.128.20
and all are not responding.

I have the following dns servers:
root@core [~]# cat /etc/resolv.conf
nameserver 209.51.143.76
nameserver 209.51.128.19
nameserver 209.51.128.20
These are also not working... I have opened a support ticket and tried fresh installs of the os... nothing is working... this is very frustrating I think I spend more time trying to make this junk work than my work!

I can ping the DNS Servers from my own computer but when on the box I can't... I cant even ping google.com by ip or domain name or vm20.unixbox.com
Can someone please respond to this?

About a week ago I found dns resolution to be failing frequently; this then stopped some important emails from getting through.
I now have the following dns servers in my resolv.conf
nameserver 209.51.128.20
nameserver 209.51.128.19
nameserver 209.51.128.17
nameserver 209.51.143.76
I did have .18 but that seemed to be the failing DNS server.
Anyone have any better lists of dns servers?

I recommend using 209.51.143.76 as the primary resolver. It is a dedicated server that runs dnscache (so it's pretty fast) and it is on our LAN.

Thanks Matt- I've changed the primary resolver to your recommended one.
My account has been around for quite some time now (on VM2) - are there other basic configurations which have changed and we oldies should know about?

From my vantage point the performance is suboptimal with 209.51.143.76
In fact my resolver skips over it sometimes due to time-out.
209.51.128.20 and 209.51.128.19 seem much faster.
