Does a website crash have a significant impact on SEO?

Question

Search Engine Optimization

Let's say there is a site with 20 thousand. + users and in the search it is in the first place. Suddenly, the developer uploaded something wrong to the site and it fell. Is it true that all SEO is down the drain? and the site is going down, all the money that was thrown at it is also down the drain. And you need to invest in SEO in a new way.

Answer 1

This is true only if the site lies ~2 weeks and completely falls out of the search engine index. I saw downtime for 2-3 days, and sometimes these happened to myself and everything is in order. After the normalization of work on the sites, attendance and traffic from the search were completely restored.
