Dear Participants,
Following the announcement on
19 December 2025 regarding the updates to the User Manual and implementation of data archiving features for ISO effective from 16 March 2026, please be advised that the maintenance window on Sundays’ noon 12:00 PM to 00:30 AM (Monday) will become a regular outage window to carry out essential data archiving processes for system implementation of ISO.
For the avoidance of doubt, the existing operating hours for weekdays (Monday to Friday) and Saturdays
remain unchanged.
TR Members are highly encouraged to consult the updated User Manual for Participants and the webpage on Operating Window for full details. The revised documentation and relevant links are provided below.
