Tracking Recently Used Channels

RFC 2811: Internet Relay Chat: Channel management

5.1 Tracking Recently Used Channels


   This mechanism is commonly known as "Channel Delay" and generally
   only applies to channels which names is prefixed with the character
   '#' (See Section 3.1 "Standard channels").

   When a network split occurs, servers SHOULD keep track of which
   channels lost a "channel operator" as the result of the break.  These
   channels are then in a special state which lasts for a certain period
   of time.  In this particular state, the channels cannot cease to
   exist.  If all the channel members leave the channel, the channel
   becomes unavailable: the server local clients cannot join the channel
   as long as it is empty.

   Once a channel is unavailable, it will become available again either
   because a remote user has joined the channel (most likely because the
   network is healing), or because the delay period has expired (in
   which case the channel ceases to exist and may be re-created).

   The duration for which a channel death is delayed SHOULD be set
   considering many factors among which are the size (user wise) of the
   IRC network, and the usual duration of network splits.  It SHOULD be
   uniform on all servers for a given IRC network.
