Why did so many people suddenly come from the search?

Question

CMS

Hello!
I have a paid kindergarten website. Usually visited by 15 - 25 people. in a day. Today, all of a sudden, more than 150 have already entered, plus a bunch of views and transitions between pages. There is a small percentage of failures - about 2 - 3.
The metric says that users are a complete zoo. Many (15 pieces) different browsers, resolutions and OS.
Everyone comes in for the usual key queries from the search for many search engines (Yandex, Google, Aport, Mail, Wolfram and many others).
By geography - all from Russia, but from completely different areas.
I definitely didn’t do anything, except for me, no one supports the site.
What do you think it could be?...

This is all news, look for options:
"paid kindergartens have risen in price"
"a child was kidnapped from a kindergarten"
"the government approved the concept of paid kindergartens in Russia"
My attendance jumped from 20 to 600 a day))
