The intermittent slowness experienced by the immigration clearance system at Woodlands and Tuas checkpoints was due to a technical glitch rather than a cyber attack, the Immigration & Checkpoints Authority (ICA) has confirmed.
Between 5.40pm on Tuesday (May 16) and early morning on Wednesday, the system experienced slowness, resulting in a slower processing time and delays at checkpoints.
In a Facebook post on Wednesday, the ICA said that the system had returned to normal at 5.30am that day.
Earlier on, an ICA spokesman said that all available resources had been deployed to manage the situation, with both checkpoints running at full capacity. Officers in the afternoon shift on Tuesday worked overtime, and night shift officers were asked to arrive early.
