The designated operator of Switzerland, Swiss Post, asks us to inform other countries and their designated operators that they are about to switch the transmission of EMSEVT events from its bespoken IT system to UPU IPS starting from 4. August 2025. The procedure is defined in such a way that one event after the other is switched over, starting with the events that are less relevant for delivery time measurements and ending with the “Start the Clock” and “Stop the Clock” events. During the transition phase, it will be unavoidable for certain events to be sent twice, firstly by the Swiss Post bespoken IT system and secondly by UPU IPS. |
