The server is back up. It went non-responsive, requiring a hard reset with nothing in the logs to explain why. The same thing happened last weekend. Most likely the hardware is failing. Although I am looking into setting up a VM replacement, I strongly recommend using a CDN (e.g. https://www.jsdelivr.com/package/npm/3dmol).
