musl libc web infrastructure is in the process of migration to the tipidee (https://skarnet.org/software/tipidee/) httpd software. This should greatly improve git repo access via https, which was previously flaky due to the non-conforming CGI implementation of thttpd.
Due to lack of support for request ranges, which are needed for friendly download support, static content is not switched over yet, but still using thttpd. We hope to have everything switched over in the near future.
