Centos can ping IP, but cannot ping domains

I have 3 servers with DO(AMS3). Suddenly, three servers at the same time faced the same issue. It seems the servers cannot connect to the outside world. I tried to ping different IP addresses and domains. Here is the result:

ping PING ( 56(84) bytes of data. 64 bytes from icmp_seq=1 ttl=60 time=2.11 ms 64 bytes from icmp_seq=2 ttl=60 time=0.946 ms 64 bytes from icmp_seq=3 ttl=60 time=0.724 ms

ping ping: Name or service not known

I searched the DO community. There were suggestions that the file “/etc/resolv.conf” might have issues. Here is my “/etc/resolv.conf” file:

cat /etc/resolv.conf ; Created by cloud-init on instance boot automatically, do not edit. nameserver nameserver

Any help is appreciated.

Thanks to the entire DO community for being such unresponsiveness and unhelpful :) It took me a couple of days but I have found the source of the problem. I have created a new DigitalOcean droplet and the newly created server had the same problem. So, I figured out there is something wrong with DO itself. I hope this helps the others with the same problem.

Hi @imanpost,

What happens when you try to curl the domain from your Droplet:

curl -IL

Does it work>

Additionally, if you telnet to port 80 or 443 via the IP and the Domain are there any differences?
