We had an issue where the m.dal.net Kiwi IRC client was unable to connect to halcyon for several days in a row. After Brandon did a /rehash throttles on the server, it started working again. It appears that ircd was enforcing throttles even though the T flag is set on the IP of the webirc gateway (23.226.229.209). Dates back to 2016-06-27.
