If you asking in terms of ranking then yes it is still working. But I suggest you should build yourself.
I know there are some PBN hosting out there who host your site on different IP’s, but we didn’t know who is our neighbor. For example your site A is hosting on 10.210.11.137 IP and site B on 126.96.36.199 IP, it means they host your site on different IP address, and hence you assume they are perfect PBN host provider but there is some problem. When they create new instance again in cloud host, then they got same class IP address which means 10.210.11.138 , on that IP they host someone else website. So here they are actually hosting your site on different website that is true, but your neighbor also using same host for PBN purpose.
