SGX announcement on the outage, around 820pm today. The reason is malfunction in power supply(?). I was anticipating a reason of cyber-attack.
A mission-critical system outage due to power supply failure, isn't an reasonable excuse...

Highly unlikely a World class exchange like SGX will resort to such excuse .
The wordings seems to imply data centre or server power failure, the main equipment went down and caused the backup equipment to kick in, but unable to cope with the transaction workload.
Not acceptable in my humble opinion. High availability systems should be well tested and rigorously run to ensure smooth failover.
Backup cannot handle the workload. Sounds like someone trying to stinge on overheads without giving sufficient headroom. Sounds familiar to SMRT?
Imagine if Singapore policy making is based on such premise. That is why there is a difference between policy making and profit maximisation and why inherently i am against the Singapore Inc mentality propagated by the previous admin
er current one no better leh though there are snail pace progress...

In normal practice of a critical system, back-up will be used in regular basic, to ensure availability. I recalled monthly switch-over was used in a critical system, to ensure both the main and backup were evenly utilized, and also a mean to ensure both main and backup are fully functional at all time.
A malfunction due to foreseeable failure, isn't an acceptable excuse, IMO.
Let's wait for MAS review comment.

I hardly hear the current admin advocate that public services should be profitable. Principles are important: They dictate what your actions will be. If one believes in value investing, that's how you will pick the stocks.
The only visible link in recent memory is the change in Temasek's mission. Temasek became another FM when GIC is already a FM. Temasek should be a VC instead focus mainly on Singapore's enterprises.

I also noticed the change. You might be aware than quite a number of VCs, and PEs established and partnered by Temasek to support newly start-up and SMEs
ya but it's an afterthought like how you and me look at S-chips
We don't brush it away but neither are we going to spend too much time on it
Like I posted earlier the idea of a listed regulator is an oxymoron in the first place

Yes! Maybe SGX doesn't believe UPS for system outage due to power supply failure? Or what? UPS also failed? So do we need an UPS for UPS for UPS....?
Further update on the outage today. The incident is a joke to me, four layers of redundancy on power supply, resulted in hours long outage on standard trigger?
-------
Source of incident identified Following preliminary investigations and analysis, the outage has been traced to a malfunction in the uninterruptible power supply (UPS) systems deployed at the SGX data centre. Power is supplied to the data centre from two separate substations. These sources are in turn connected to
individual UPS systems providing four layers of redundancy. Resulting from a momentary fluctuation in power supply from the substations, the UPS systems
switched to its internal power source. However, the internal power source in both UPS systems malfunctioned.
