The disruption in 3G mobile coverage to M1 customers was caused by a power switch incident, the network provider said in a statement.

According to M1's statement, a power incident at 3am on Jan 15, during an equipment upgrade at M1's network centre, set off the gas suppression and water sprinkler systems, which in turn caused an outage to one of our mobile network switches.

This caused service disruptions for some of M1's customers in the southwestern parts of Singapore, in the West Coast, Jurong and Tuas areas.

2G services were not affected by the outage.

To restore services, M1 has connected the affected part of the network with a working switch and are conducting final stages of testing. Actual migration of traffic from the affected switch will take place progressively, M1 said.

Customers can get updates on the situation through M1's website, Facebook page and hotline.
