Hong Kong Exchanges Says Website Traffic Exceeded Normal Levels

Hong Kong Exchanges & Clearing Ltd.’s website was disabled yesterday after traffic exceeded normal levels, said Chairman Ronald Arculli.

The exchange is planning to review its entire technology infrastructure, he told Bloomberg Television. The city’s bourse yesterday suspended seven companies in afternoon trading, including HSBC Holdings Plc (HSBA) and Cathay Pacific Airways Ltd. (293), after its website was hacked.

“There was an awful lot of traffic coming into our website,” Arculli said in an interview from Hong Kong. “Due to the instability of it and because we were aware that companies were making announcements, we really had no choice but to suspend trading of those particular companies.”

The bourse joins companies from Sony Corp. to Citigroup Inc. and Nasdaq OMX Group Inc. that have been targeted by hackers. Hong Kong Exchanges said today that the website has resumed operation.

Arculli also said the Hong Kong bourse is not in any talks with other exchanges for a merger or acquisition.
