cloudload.comは安全ですか？

On www.cloudfront.com/#, supposedly "Plans and Pricing". In the page center a Downloud Slider appeared and seemed to be downloading, or Uploading something. After a few seconds of this the slider completed and was replaced with a VERY DISCONCERTING STATEMENT: "DOWNLOAD ADDED!" I didn't request a Download or an Upload - and I don't know if this site has uploaded my personal information to it's "Cloud" or not - what is very unnerving is that I HAVE NO WAY OF KNOWING. (I have no Account with them.) I DON'T FEEL COMFORTABLE WITH THIS SITE - AND I FIND IT VERY SUSPICIOUS ACTIVITY. If this is an innocent occurence I suggest the Owner of the Site change this and make the site 'FEEL' more secure and trustworthy. I made a screenshot pertaining to this event and will add it if I can find a way.
