Are the Smush servers working?

For over 6 hours, the message displayed on my site's WP Smush Pro Admin page has been:
"The smushing elfs are busy, You are 2nd in queue.
Current wait time: 2.5 hours"

Despite refreshing the page, the wait time has not changed. All of the images have been sent for smushing; none of them have been fetched.

I just tried to individually Smush one image on a different site and received the message:
"Oh Snap! Seems like Smush Pro server is not reachable, you can try back in some time."

Are your Smush servers working? And if they are not, how do I cancel the bulk "smushing" that seems currently to be stalled?
