Why can I not ping microsoft.com, amazon.com, or another site?

Updated: 04/26/2017 by Computer Hope

Some popular sites such as amazon.com, microsoft.com, slashdot.org, and other sites that have had DoS attacks in the past may filter ICMP to prevent ping requests. Because of this when pinging these domain names or their associated IP addresses you'll receive a "Request timed out" or get a "100% packet loss" error.

Amazon.com not responding to ping request

Because this is a legitimate way to configure a website, you should not be concerned if a particular address does not respond to your pings. (It's nothing personal.) However, if you are getting this response from every website, you may be experiencing issues with your network. See our network help overview for additional help troubleshooting your network.
