Following the news that the Trump Hotels website is displaying a “Checking your browser before accessing Trumphotels.com” notification upon loading the page—a strong indication the site is in full defense mode against distributed denial-of-service (DDoS) attacks. Kyle Wilhoit, Security Researcher at DomainTools commented below.

“Cloudflare is a service often leveraged by nefarious actor and concerned organizations alike. Currently, the Cloudflare loading page is no longer present. However, after looking at the domain in our Iris tool, I noticed Trumphotels.com IP and Nameserver were still tied to Cloudflare. So, it seems Trumphotels.com took down their Cloudflare landing page, but are still hosted by Cloudflare. It looks like Trumphotels.com changed over to using Cloudflare in September of 2016. (Roughly) This means they are still using their services, they just aren’t displaying that as outwardly as before.”
