Everything is up.

It's just a little touchy, sometimes it shows zero if there are network timeouts while trying to retrieve live stats from the mining server. This will be improved as I rewrite the software controlling how the servers communicate with each other (current top priority).

If the live stats aren't working but mining is working, it is still safe to mine. And you should still see accepted proofs of work ticking up if you load the workers list, wait a minute, then refresh.
