Thanks so much for reaching out!
I’m glad to hear that things are working now!
It’s difficult for me to provide more information on why this happened, as I haven’t heard other users report this issue. You may want to consider setting up some kind of caching yourself through a plugin or through your hosting provider in order to prevent this from occurring again.
Here is more information on caching basics:

Let me know if you have any other questions on this topic!
Thanks,
Jaime
