Tip of the day: Channel mode +P makes a channel permanent. The topic and modes are preserved,

even if all users leave the channel, and even if the server is restarted thanks to channeldb.

Connthrottle

By default, the Connthrottle module is enabled in UnrealIRCd. When a server receives a high amount of connection attemtps (is under attack) this will allow known users without restrictions but will limit the amount of unknown users to a certain rate, such as 30 connections per minute. This does not prevent a drone attack completely but it limits the damage a lot, giving you and your fellow IRCOps time to act.
