MyRepublic: Issue caused by upstream service provider

A total of 45,637 users were affected by the outage, according to The Straits Times.

MyRepublic’s consumer vice-president Terry Williams was quoted as saying that the outage was caused by "an upstream equipment provider that was not supposed to be service impacting", and that it had occurred during maintenance which was part of network upgrading works.

Williams also said that while the fix is "instantaneous", some users need to restart their optical network terminals (ONTs) or modems to restore connections, and that those who have done so are now back online.

As for whether such disruptions take place often and whether a similar issue has happened, Williams replied, "No, not in recent years."
