Major internet service providers reported that a routing fault affecting residential subscribers was cleared after overnight maintenance.
Customers in several districts experienced slow speeds or intermittent disconnections between 11pm and 4am.
Providers apologised for the inconvenience and said credits would be applied automatically to affected accounts.
The fault originated at a regional routing node that handles traffic between residential networks and international content servers. Engineers identified a misconfigured firmware update as the likely trigger and rolled back the change during overnight maintenance windows.
Customer service hotlines reported elevated call volumes through the morning as remote workers reconnected to office systems. Providers deployed additional staff to process rebate enquiries and confirm that home broadband speeds had returned to normal levels.
The Infocomm Media Development Authority said it is reviewing incident reports from major providers and may issue advisory notices if recurring patterns emerge during peak usage periods.
