Video classroom classes down for anyone else?

Are video classroom courses down for anyone else? Getting the Server Error 500 across all VC classes for nearly 4 hours now. Have had the learning subscription now for only 16 days and it's the 3rd time it's happened. The first time it came back within 30 minutes so figured it was just something transient. The second time I lost a day I was planning on studying. Also lost today. Managed to get in once today and got about 90 seconds into the video before it started buffering and then nothing but server error 500's. Extremely frustrating.
