I think the answer to that is having a properly diversified (by node operators, data centers and geolocation) collator set - determining the right size of it is another topic but in my point of view, anything above 30-40 should be sufficiently safe for the sake of decentralization and liveness. Don’t forget that only one online collator is enough for parachain to produce blocks.
