I am not a trader so it does not really bother me whether SGX delay trading today to 1230 hours or not. However, I am very puzzled that in these days of cheap availability of hardware redundancy, sophisticated software availability capabilities, SGX is still CONFRONTED WITH THE NEED to issue an unexpected outage of half a working day. This clearly is UNACCEPTABLE in my view.Remember, running an operation 24X7 is not a new concept or requirement. Already more than 25 years ago, it is already a key requirements in most major data centers.
If I am in charge of SGX, I would have fired the CIO on the spot.
