It looks like the maintenance didn't go as smoothly as I had expected. All I get from the stream is a high-pitched whine, and I can't get into the studio now, as it it 11:48 PM. I suppose it could be a problem with the computer playing the music, or it could be an audio driver bug (the maintenance included a kernel update to fix a rather nasty local root exploit). I will investigate as soon as I am able.
