Do 301s still work after hosting is discontinued?

[Caro-O]

I am in the process of phasing out a website that has been acquired by another company.

Its web pages are being 301 redirected to their counterparts on the website of the company that has acquired them.

How long should I maintain the hosting of the phased out website? Technically, do 301s still work after the hosting has been discontinued?

Thanks, Caro

If you're 301 redirecting site A to site B, if you quit paying for or sell hosting/domain for site A, then the 301s will cease to work.

Thank you Erica.
