How long does it take for websites to drop out of the search index if they are unavailable?

Question

Google

The server has died. Decided to buy a VPS. I have been waiting for two days for a response from OVS, apparently they do not work on weekends. As a result, I made an order from hetzner.
And what do I see? These Europeans also work only on weekdays.
Those. they will raise me a bare ubuntu only on Mon-Wed, then + a day for the census of dns servers. In total, it turns out that my sites will be unavailable for a week, is it likely that everything will fly out of the search index? Or will everything be fine?

Answer 1

mmm.. well if you have 503 server response
bad if 404 and other
Positions will drop, but not for long
