My iPad will not load certain websites

Hi All,

Beginning yesterday morning, my iPad (running iOS version 11.4.1) will not load a couple of local newspaper websites. All other sites seem to load fine. When you try to load these sites, the page stays blank, and the little wheel beside the wifi indicator just spins endlessly. There is no failure to load or any error message. This occurs when using Safari, Edge or Chrome as the browser. The same issue occurs on my wife's iPad. Our other devices include 2 iphones (iPhone 6 and iPhone7, both with iOS 11.4.1) and a Microsoft Surface Pro 3, and each of these devices are able to load these web sites without issue. I am able to ping the site (using Mocha Ping Lite), but a traceroute times out at ...cloudfront.net.

I am an IT Professional (almost 40 years in the field), and I've exhausted my troubleshooting skills on this.

Any help would be appreciated.
