M1 tweaks site switches, software after outage
M1 is tweaking its site switches and software in the wake of a service disruption which lasted about five hours last week, it said yesterday.
The telco also said that a preliminary investigation of the disruption found that a pair of mobile site switches which acted in an "unstable manner" had caused "intermittent connection problems" between its switches and customer base. "The cause of this is still being investigated by our vendor," M1 said in a statement yesterday.
Last Tuesday morning, M1's customers faced difficulties making voice calls, exchanging text messages or accessing mobile data. The industry regulator, the Infocomm Development Authority of Singapore, had expressed its concern, noting M1's other outages over the past year.
