Jetpack image accelerator hosted images return 502 bad gateway error

Hello,
On the page link above, I have begun to get broken links to some images. I am using Jetpack’s image accelerator, and when I click on the broken link, I get a Bad Gateway 502 error.

If I turn off image accelerator, the images again appear, so there doesn’t seem to be anything wrong with the files I uploaded.

Is this just a server that’s temporarily down, or some more permanent problem? I can just turn off the image accelerator, but my pages are pretty image heavy, so I like that they load faster with it turned on.

Thanks for any help,
Jim
