I am facing an issue with DNS resolving in my droplet. I can’t ping even Google’s DNSes:

[root@xenonon etc]# ping 8.8.4.4
PING 8.8.4.4 (8.8.4.4) 56(84) bytes of data.
^C
— 8.8.4.4 ping statistics —
5 packets transmitted, 0 received, 100% packet loss, time 4814ms

Here is content of my /etc/resolv.conf:

[root@xenonon etc]# cat /etc/resolv.conf
nameserver 8.8.8.8
nameserver 8.8.4.4
nameserver 82.215.0.115
nameserver 209.244.0.3

When I try to install something by yum, I am getting following error:

[root@xenonon etc]# yum install traceroute
Loaded plugins: fastestmirror
Setting up Install Process
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=6&arch=x86_64&repo=os error was
14: PYCURL ERROR 6 - “Couldn’t resolve host ‘mirrorlist.centos.org’”
Error: Cannot find a valid baseurl for repo: base

What is going on?

Thanks,
Maksym.
