PLEASE NOTE: Affected services/systems are subject to change. While we try to ensure that we get as much information as possible to our users well before scheduled maintenance there are unavoidable changes that need to be made as we learn of packages/services that are out of date. Expected downtime for each service that needs to be restarted is ~20-30min. If you are on an IRC server that goes offline on 06/23 try to connect to another server, or simply wait until that server comes back online
If you are online at the time that IRC services (Anope) is restarted, you may need to identify for your nick again. Don't worry, we don't update IRC services very often due to long periods between releases.
