The review queue Reopen Votes seems to be malfunctioning.
When I try review questions, it says loading item , but it never finishes.
Unexpected response code: 503
I've tried the latest versions of Chrome and Firefox (Ubuntu). The remaining review queues are not affected.
I'm not sure if this is a network wide issue. The few other sites where I have access to the Reopen Votes review queue don't have any pending questions.
