I found ayumilove's comment on Reddit about this-
"Hi all, the website is down due to some issues that I'm still investigating. It causes my website to crash due to high CPU usage. I'm currently working with the hosting provider to see how to bring the site back up. They have suggested several site optimizations which I have already implemented. I have not been able to get their response quickly especially on weekends, hence the site will be down longer. I have been working on this issue for the past 4 days and its super frustrating and tiresome. :("
Here's the full thread
