Matrix-Libera IRC Bridge Temporary Shutdown, a Retrospective (2023)

Update: We no longer have an official Matrix bridge. Please see our FAQ about Matrix for more information about using Matrix on Libera.Chat.

Operating under assurances that failed connection and messaging attempts would not be bridged, we began to relax our abuse mitigation measures, only for some of those bots’ puppets (on homeservers that had not been cleaned up) to reconnect to Libera, join channels, and send “federation delayed” spam even half a year later. Furthermore, these returning bots were consuming a portion of the bridge’s connection limit, and also contributed to some misconfigured Matrix rooms filling channels to the point of overloading some clients because the idle puppet cleanup process could not work. There have also been several serious outages this year which EMS failed to notice until Libera staff put substantial effort into documenting the symptoms in the coordination channel, often needing to find alternative ways to make contact when no response was forthcoming.
