Seems to be related to Bryan's Monolog deployment earlier

uses abuses wfErrorLog() to send udp packets to a custom endpoint. The conversion of the logging configuration for the group0 wikis to Monolog has changed the internal behavior of wfErrorLog() such that the events are not redirected to the custom UDP endpoint any longer.
@Legoktm started a patch quite a while ago to put the UDP packet formatting and sending logic in a more general place. Fixing that patch up and changing UDPRCFeedEngine to use it is the right way to fix this bug.
This should be fixed or block further deployment to phase1 or phase2 wikis as Countervandalism tools (including ClueBot, CVNBot, Huggle and what not) all depend on the irc feed. Without this those applications will never see this edits, and neither their users. This can have near-unrecoverable impact on most wikis in terms of cross-wiki abuse, highly-visible vandalism, and subtle vandalism as well.
I agree and will not be proposing any additional configuration changes to propagate the Monolog logger past group0 until we have a fix for this deployed. Note that this is not a problem in the MediaWiki code that is on group0, it is a specific configuration of the logging layer (https://gerrit.wikimedia.org/r/#/c/179370/ & https://gerrit.wikimedia.org/r/#/c/179958/).
