CloudFront May be Blocking us?

Hi All: This seems to be happening more than I would like! Nearly every day I 
visit
www.dvidshub.net
All was fine until maybe last Wednesday when I began seeing an error 403, but 
even unchecking a user-agent didn't help, as I saw a Coud Front error. I did 
contact dvids support, who asked for a screeen shot. But in trying to contact 
cloudfront, not only are they saying support for IE ended on July 30, but 
without java I cannot submit a ticket. And no, L Y N X is certainly not an only 
browser where I cannot connect. As an experiment, I was able to connect on my 
Wife's windows7 machine. This site is valuable in finding out about 
live-and-recorded Defense Department videos. Thanks so much in advance
