Blackout hits M1's 3G service partially

Many M1 mobile-phone subscribers were left irate yesterday after a power blackout resulted in the loss of 3G network services in the south-western part of Singapore.

The incident, which occurred during a transmission-equipment upgrade at 3am, led to the blackout of a mobile-network switch, said M1 in a statement yesterday. Services, which affected subscribers in West Coast, Jurong and Tuas, were not fully restored by press time yesterday.

Subscribers were updated through M1's Facebook page, its corporate website and hotline, said the telco.

M1's online posts advised affected subscribers to use the telco's 2G network temporarily, while engineers worked to restore the service.

"The 2G network entities are connected to another switch and were not affected," said M1.

M1 chief executive Karen Kooi apologised for the inconvenience caused and said that added measures will be put in place to "prevent recurrence of such incidents".

Sales executive Ken Peh, 32, told My Paper that he first realised he could not surf the Web on his phone at about 6am yesterday while he was at his office in Jurong. He said: "I restarted my mobile phone several times and even had trouble sending and receiving messages, as well as making calls."

The Infocomm Development Authority of Singapore (IDA) said that M1 reported the incident. A spokesman said: "IDA will investigate the service outage thoroughly under the Code of Practice for Telecommunication Service Resiliency and take the necessary actions if there is a breach of the code."
