Yeah, looks like I'm out of capacity on my workers right now - this is the first real burst of traffic I've had.
As far as I can tell, all jobs are either queued or running, so it should complete for you at some point.. not sure if I can get an ETA for you though.
Hey Michael, it looks like there were some errors with a few optimization jobs, including one of yours. If you want, you can try re-queuing the job by refreshing and then clicking on the button again.
