StarHub's net disruption not due to DDoS: IMDA
It was caused by telco's failure to deal with legitimate surge in traffic rather than a denial of service attack

On the nights of Oct 22 and 24, 2016 some home fibre broadband customers in several parts of Singapore encountered intermittent difficulties in accessing the Internet as StarHub's DNS (domain name system) servers could not fully handle the high volume of Web requests. The problem lasted 130 minutes on Oct 22 and 55 minutes on Oct 24 before StarHub managed to control the situation.
DNS servers run special-purpose networking software which translates a Web address, such as www.starhub.com.sg, into a machine-readable set of digits that allows various devices to connect to the website.
