Other M1 customers – including its mobile broadband and cable modem users – do not seem to be affected for now. It is not known if SingTel or StarHub fibre users are having this problem, though M1 users have gone online to forums and confirmed the difficulties faced. The problems come just a day after SingTel mobile users cried foul over being cut off from their calls, SMSes and Net surfing due to a software glitch. Seen together, the incidents will likely focus the spotlight on the seemingly frequent network disruptions of late, as Singapore zooms past a broadband penetration rate of more than 100 per cent when it comes to homes using wired broadband services. The reason for M1's latest outage is still unclear. However, an M1 call centre operator told this Techgoondu writer minutes ago that the telco was working to recover its services with Nucleus Connect, the operating company for Singapore's fibre network, which is responsible for some of the network switching and other operations.
