Law suit shuts down Olson TZ database servers.
I've pulled the court documents via Bloomberg Law. The issue at hand is that Astrolabe owns copyright to the "ACS Atlas", consisting of both the "ACS International Atlas" and the "ACS American Atlas". Olson tz files specifically reference the "ACS Atlas" as a source for some tz data and allegedly incorrectly asserts that it is in the public domain. They sent a takedown notice in May 2011 and it was ignored. The FTP site is listed in the court filing and they are requesting a temporary injunction, a permanent injunction, and award of damages and attorney fees.EDIT: The registered copyright they're referring to is here:
