Hello, Thank you for your question. The easiest way to tell if you are Blacklisted is to navigate to the site, and you will get a connection error if you are blocked. You can also Ping your domain, and it will not respond if your IP is blocked. You can then use a site such as downforeveryoneorjustme.com to see if the rest of the world is able to navigate there. If you have any further questions, feel free to post them below. Thank you, -John-Paul
