We will be performing island-wide preventive maintenance on 21 June 2004. During the maintenance, there may be a brief period of service disruption to facilitate the work. However, the maintenance work will be carried out only during off-peak hours from 2am to 6am so as to minimise any inconvenience to our customers.
We seek for your kind understanding as we work towards optimising the performance of our network for the enjoyment of all our customers.
