Usage: SQUIT <server> <reason>

Causes the specified server to be disconnected from the network. Use the /connect command to connect the server back to the network.

/squit irc.webmaster.com I want to connect you to another hub.

This is done to reroute a server A server cannot connect to another server on the same network. So you have to squit a server before you can reconnect it. You might wish to globop before rerouting, in case someone has a good reason not to reroute. It is also nice to wallop before squiting so that users who wish to be kept informed will expect the split.
