Can not access domain, ping of a domain returns 127.0.0.1 IP address

Symptoms

• When pinging a domain, it responds from 127.0.0.1 IP address:

  # ping example.com
  PING example.com (127.0.0.1) 56(84) bytes of data.
  64 bytes from localhost.localdomain (127.0.0.1): icmp_seq=1 ttl=64 time=0.046 ms

• DNS records for the domain were changed/updated recently.

• When checking DNS propagation for example.com, and a specific record (e.g. A) at some external resources, for example, whatsmydns.net, in some geographical locations the domain is resolving to 127.0.0.1, whereas in others it is pointing to the correct IP address.

• Dig utility has expected output when query sends to certain DNS server which is specified in DNS settings of doman, and no output in other case:

  # dig +short example.com @203.0.113.2
  203.0.113.2
  # dig +short example.com 
  #

  Where 203.0.113.2 is IP address of the server where domain hosts.
• File hosts does to contain any domain relevant entries.

Cause

DNS for the domain has not yet been fully propagated worldwide.

Resolution

Wait from 24 to 72 hours for the DNS records to be fully propagated worldwide.
