there are many different mining pools and each single pool owns multiple different servers in different locations. so for example when you see F2POOL has 15% of the hashrate, that is being spread among multiple servers not just one to be shut down with a natural disaster or any other thing. so for example it could be 3 different 5% servers.
if you look at their coinbases they sometimes even include the server name in it too.

additionally as it was mentioned it is miners who connect to these servers and if one went down they simply switch to another one. although this can take some time but it won't harm the bitcoin network in any major way. worst case is seeing a small rise in the time between blocks that are found until miners make the migration.

To be honest i just know about this.

To kill a pool is not enough for 51% attack. However, if somebody (gov, for example) will have enough money they may buy hashrates and do it in other way

and yes for now its seems impossible to do that even government. in fact what would any gov to risk their money to do this Grin
