Hi Jessica,
Your site is loading fine here, but it looks like the server is denying your request because you are connecting from a known spamming IP address. This means that your IP address is listed on an external blacklist, so the server is blocking your request to prevent spam bots touching your site.
Please could you check whether you have a proxy or VPN enabled on your computer, and try disabling it? It's fairly unusual for normal visitors to be blocked by these checks.
You can find out more information by entering your IP address here:
