Not getting ping response on CentOS server hosted with DigitalOcean

I have a CentOS server with DigitalOcean , i am trying to ping "1c-bitrix.ru" , i am getting the following PING 1c-bitrix.ru (46.235.53.93) 56(84) bytes of data. but there is no response.

I tried the same from my Mac and its working properly. My IPTables are as follows

Chain INPUT (policy ACCEPT)
target     prot opt source               destination         


Chain FORWARD (policy ACCEPT)
target     prot opt source               destination         

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination  

**Update

I ran a traceroute on 1c-bitrix.ru and see the packets are getting dropped in middle and not reaching destination. I did the same from other computer and it works fine , so there is no issue on the destination side.
