Photobucket not loading

About half the time when I click on a link to a picture on Photobucket, the image doesn’t load. I just see a grey frame. It may take several reloads to see the picture – even from my own Photobucket account. Yesterday, someone posted a link in GQ to a Photobucket video, and I was never able to get it to load.

Has anyone else had this problem? What’s going on?

I’m using Safari 10.0, but this happened with the previous version as well.
