About a month ago, I began having an inability to load the website parkwhiz.com. The IP appears to resolve, but any pages from the website will fail to load and ping attempts will hang with no response. I determined that this appears related to use of 1.1.1.1 DNS servers, as I am able to load the site when connected through a different DNS provider.
