Title: When site crashes, have error message recommend my mirror site.
My mirror site is https://offline-os.glitch.me. So far it has had positive reception from the community whenever I have posted a link to it when the site was down. I don't like having to paste the same link to people over and over again though, which is why I am making this suggestion. The only problem is that the instruments have started to not load, so I fixed that bug. It should work now.

Thank you for making it! I appreciate it a lot.
