This article is rather misleading. The plan to move the TZ database to IANA is over a year old - see https://datatracker.ietf.org/doc/draft-lear-iana-timezone-da... - though the lawsuit has sped the process up a bit. The TZ mailing list switched to IANA within a day of Olson shutting down the old list, and Robert Elz has been acting as interim maintainer. There has been no disruption to TZ database maintenance. IANA are not yet providing web or FTP sites for distributing the database and code.
