I just noticed this today, try to download any asset on any releases page and it will show a 500 error page.
Here is an example on Ollama, llama.cpp, etc:
https://github.com/ollama/ollama/releases/download/v0.9.1/sha256sum.txt
https://github.com/ggml-org/llama.cpp/releases/download/b5688/llama-b5688-bin-macos-arm64.zip
You will get a 500 error page from GitHub.
Does this happen with anyone else?
