Why is IRC distributed across multiple servers?

I have been wondering for a long time why IRC networks have multiple servers. Wouldn't it be simpler just to use a single server?

One of the problems of having multiple servers is that netsplits can occur. Anybody who has been on IRC for a while will have witnessed one. Hundreds of people suddenly ripped out of the chat. This can also screw up channel and user modes, and 'some people' have been known to wait for netsplits in order to takeover channels or enter password protected channels.

So lets compare situation (A) a single IRC server everyone connects to with the current setup people use (B) multiple servers. Let's say you run an IRC network with u = 40,000 users and n = 20 server nodes that people connect to via round robin DNS (meaning that when people resolve the DNS it gives them a random server from the set of 20 to connect to). These are vaguely realistic numbers modelled after libera.chat.

So in (B) you have roughly u/n = 2000 clients connected

        for password in passwords:
