There is a new certificate for LLVM.org and HTTPS is enabled for the website. We know of a few issues with some of the webpages but will be working them out over the next few days.
Please do not hesitate to contact email@example.com with any issues you find. With a large change like this, we expect to have a few bumps and appreciate your patience.
A huge thank you to Anton and Mike for all their hard work!
