I'm forwarding this heads-up for the shutdown of the well-known NTP server swisstime.ethz.ch on behalf of the ETH Zurich. -- Alex SWITCH NOC AS559 Date: Tue, 25 Jun 2013 07:12:54 +0000 From: Wittmann Armin <[email protected]> To: "[email protected]" <[email protected]>, "[email protected]" <[email protected]> Subject: Filtering of NTP-access to swisstime.ethz.ch as of July 1st, 2013 *** German version below *** Dear NTP-Users of swisstime.ethz.ch After we changed the NTP use of swisstime.ethz.ch to ClosedAccess at the end of 2012 we tried contacting the main users of this service (via whois) for a six month period - unfortunately with minimal success. As of July 1st 2013 the time has come. SWITCH will block NTP-access at the border to Swiss NRENs so that commercial users and universities/ technical colleges (outside Swiss NRENs) will no longer be able to access swisstime.ethz.ch as a time server. This is for your information as well as for others who may be affected by this change.

Juli 2013 von ausserhalb des CH-NRENs Geschätzte ntp-User von swisstime.ethz.ch Nachdem wir Ende 2012 die ntp-Nutzung von swisstime.ethz.ch auf Closed Access reduziert haben, wurde während 6 Monaten versucht die Hauptnutzer des Services über whois-Einträge zu informieren, allerdings mit mässigem Erfolg. Per 1. Juli 2013 ist es nun soweit. SWITCH wird den ntp-Zugriff am Border zum Schweizer NREN blockieren, so dass kommerzielle Nutzer und Universitäten/Hochschulen ausserhalb des Schweizer NREN swisstime.ethz.ch als ntp-Server nicht mehr nutzen können. Dies zu ihrer Information und möglichen Weiterleitung an andere betroffene Kreise.
