Network Management Guide for 123NET fibre Internet Services

123NET fibre is committed to providing an excellent user experience that supports any lawful product, service, or application that its subscribers choose to access through their 123NET fibre Internet service.

To do so, 123NET fibre engages in reasonable network management practices. Descriptions of these practices are provided below for informational purposes only and may be subject to change at any time.

Use of 123NET fibre’s Internet services is governed by various service terms and conditions that are available here ( The information provided below does not change the rights or obligations under those terms and conditions of either 123NET fibre or the subscribers to 123NET fibre’s services.

Congestion Management

In the unlikely event that users' aggregate demand exceeds the available capacity of the network and creates acute congestion, 123NET fibre will employ various techniques to ensure that subscribers continue to have a positive experience. In times of acute congestion, 123NET fibre Internet service bandwidth will be fairly allocated among subscribers without regard to the subscribers’ online activities or the protocols or applications that the subscribers are using. While acute congestion is occurring, subscribers will still be able to use the lawful content, services, and applications of their choice, but this fair sharing of bandwidth may result in slower download and upload speeds and slower response times from websites and Internet-based applications and services. 123NET fibre will not engage in deep packet inspection (where the content of the data packet is inspected beyond its IP, TCP, and UDP headers) or drop specific types of end-user Internet traffic except as described herein to preserve the integrity of the network and protect against negative effects of Internet threats.

123NET fibre does not prevent or impede the use of any other product or service that its subscribers choose to access over their 123NET fibre Internet service as long as the use of that product or service does not violate the service terms and conditions. 123NET fibre also does not favor or inhibit any applications or classes of applications except as described herein.

The advertised speed of the subscriber’s chosen 123NET fibre Internet offering is the maximum speed expected to be achievable for that service offering. Several factors may affect the actual speed of 123NET fibre’s service offerings at any particular point in time. These factors include, but are not limited to: the capability of the subscriber's device used to access 123NET fibre; the capability of the business network between the subscriber's device and 123NET fibre; the capability of websites or other Internet services accessed by the subscriber; the connectivity and capacity of Content Delivery Networks (CDNs); the subscriber’s use of 123NET fibre TV service (if applicable); and network congestion/other Internet traffic.

Network Security

123NET fibre engages in network management practices intended to address threats to its network and subscribers. 123NET fibre reserves the right at any time to take action necessary to protect the integrity of its network and other parts of the Internet. This may include terminating or suspending service to subscribers who engage in activity that violates the 123NET fibre Terms and Conditions, including but not limited to activity that threatens to undermine the integrity of 123NET fibre’s network or services.

123NET fibre uses industry standard tools and generally accepted best practices and policies to prevent subscribers and other Internet users from experiencing the negative effects of Internet threats such as viruses, spam, denial of service attacks, and other unwanted or harmful online content and activities.

Please notify 123NET fibre of any perceived network security or other Internet threats.

Attachment of Devices

123NET fibre’s subscribers may attach any device of their choice to the 123NET fibre Internet service that is compatible with the 123NET fibre network (i.e., supports IPv4 and/or IPv6 via Ethernet or Wi-Fi technologies), does not violate the 123NET fibre Terms and Conditions, and does not cause harm to the network, other users, or the provision of Internet access service. The performance a user experiences may vary depending on the capability and configuration of devices being used on the service.

Special Information Regarding Wi-Fi Routers

123NET fibre may provide each of its subscribers a Network Box, which excludes built-in Wi-Fi and includes a gigabit ethernet port. 123NET fibre highly recommends the use of encryption with your Wi-Fi router device. Encryption will help prevent unauthorized users from accessing a subscriber's business network.

123NET fibre subscribers are responsible for activity that occurs over their connections, including unlawful use by third parties. While Wi-Fi encryption does not encrypt traffic that a subscriber sends over the Internet, it does provide encryption for the Wi-Fi portion of the communications path between the subscriber’s wireless device and the subscriber’s Wi-Fi-enabled router and/or TV Box. In the Support Centre, 123NET fibre provides step-by-step instructions for activating the encryption setting.

For information on accessing and configuring features in 123NET fibre Wi-Fi enabled device(s), please visit the Support Centre.
