Don't build your site around an app that can be removed from app stores or other big-tech platforms.
Host your entire infrastructure from database to web servers and supported services. Use open-source and custom software that can't be shut down on redundant servers.
Have backup domains from different domain name providers so you have fallback addresses. (and publicize them)
Have plans for heavy traffic (success) and network attacks.
