Sysadmin Alternative Public DNS resolvers from Google 8.8.8.8 and 8.8.4.4

I Just came across a DNS resolver issue with some of my VPSes which by default set in /etc/resolv.conf the following Google public dns

Code:

nameserver 8.8.8.8
nameserver 8.8.4.4

However, I couldn't ping out anywhere, so had to try alternative public dns which worked.

I used Comodo Secure DNS Comodo Secure DNS, Managed DNS Service, Secure DNS Provider

so

Code:

nameserver 8.26.56.26
nameserver 8.20.247.20

So something like

Code:

options rotate
options timeout:1
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 8.26.56.26
nameserver 8.20.247.20

Note this won't help with ping tests out as ping looks up the first instance and exits so never gets to try further down the rotation.

Just a heads up for folks

 

well for me the vpses had been running for a few weeks without problem so only happened just today so probably a glitch for 8.8.8.8 for a while
