Thanks for explanation achow101. Does it mean that DNS seeders (primary and built in) are set of "hardcoded" servers which are basically critical point of bitcoin core and if those servers won't be available whole blockchain will stop functioning (as eventually nodes won't be able to discover each other)?

No. Nodes can still discover each other without the DNS seeders. The DNS seeders can be swapped out with some other initial discovery process too.

Furthermore, as I said, nodes maintain their own internal database that persists across restarts of nodes that it can connect to. So it will use those nodes instead of the DNS seeders on all starts after the first start. For new nodes, new nodes will fall back to the hundreds of hard coded seed nodes.

Lastly, nodes can be added manually too.

Ah, ok. Thanks for clarification!
