HKEX enhanced its website and related systems before the implementation of the Electronic Disclosure Project on 25 June 2007, and it has installed a back-up system and developed disaster recovery arrangements to ensure business continuity. Before implementation of the project, HKEX performed a series of tests and invited related parties (including listed companies, their agents and information vendors) to participate in the testing and familiarisation sessions.
If there is a double failure of the HKEX website and its back-up website systems, HKEX has made arrangements to disseminate information on listed company announcements on a third party’s website. HKEX will announce the website when necessary. Furthermore, listed companies are required under the Listing Rules to publish their announcements on their own websites, in addition to publishing them on the HKEXnews website. Therefore, investors can access listed companies’ latest announcements through the companies’ own websites if the HKEX website fails to provide service.
Moreover, various Internet service providers have been engaged to minimise any negative impact on the HKEX website of the sub-par performance of any single service provider, to ensure stable website service for the public.
In cases of widespread Internet access problems in Hong Kong, the impact would not only be limited to the dissemination of issuer information. Various aspects of market operations would also be affected. HKEX may then have to invoke contingency measures and inform market participants and the public of the arrangements through any available channels.
