An incident report (embedded below) purportedly by the Infocomm Development Authority of Singapore (IDA) has determined that “routing problems” from an unnamed Internet Service Provider (ISP), along with the hardware failure of an internet router, were the causes of the massive outage that took down over 19 government websites last Saturday. The report did not state if human error or hackers were involved.Read more (Report blames outage of Singapore government websites on ‘routing issues’, ‘hardware failure’)
The document, uploaded by an unknown person, says that GDC1, an internet connection service used by many government websites, called for an urgent scheduled maintenance on November 1 from 1pm to 3pm to test “the implementation of a security solution for internet access”.
However, things started to go wrong during the test. When the internet connection was swung from its primary to secondary link, a “routing problem” was discovered on the side of the Internet Service Provider, which caused the swing to fail.
But when the internet connection was reverted back to the primary link, the internet router experienced a hardware failure. Even though a replacement router was eventually used, it had difficulty connecting to the ISP.

This affected selected government websites.
IDA explained this was due to a combination of a routing issue and a hardware failure, resulting in a glitch in the system.
However, this was rectified by 5.20pm.
