Factors inside your premises

Router/Modem

We advise customers to use the router or modem provided with your service (if one was provided). We test the devices we supply to ensure they're capable of delivering the bandwidth that you've signed up for. If you choose to use your own router or modem, you'll need to ensure it is suitable for the level of performance required.

Computers/Servers

For speeds above 100Mbps, older computers may struggle. We recommend that for services over 100Mbps your computer specifications meet or exceed the performance of an Intel i5 6th Generation CPU and have a Gigabit Ethernet NIC (wired) or 802.11ac support (wireless). If you are running speed tests then we recommend that you use an up to date web browser as older browsers have poor JavaScript performance, and pick servers in Auckland that are connected to the AKL-IX or MegaIX Auckland peering exchanges.

Wi-Fi

Wi-Fi can significantly impact on your experience. Even if you're using a wireless router or access point supplied by Vorco, you should be aware that throughput will decrease as you move further away from the wireless router or access point, and because Wi-Fi operates on unlicensed frequencies it is subject to interference from sources such as other nearby networks, building materials, cordless phones, baby monitors, radios, microwave ovens and Bluetooth devices.

Other Users

If you have multiple users on your connection you should keep in mind that if your connection is 100Mbps and another user or program on your computer is consuming 20Mbps, you will not exceed 80Mbps on a speed test.

Internal Cabling/Switching

Older cabling in your office may not support Gigabit Ethernet. We recommend all internal cabling and switching is at least Cat6. If your internal network uses 10/100 switching then you will be unable to achieve more than approximately 80Mbps on a speed test. This is because 100Mbps layer 2 throughput (on a 10/100 switch) translates to around 80Mbps layer 3 IP throughput.

Factors outside your premises

Distance to Host

The physical distance between you and the content you are accessing. Internet performance is restricted by the speed of light. This means a server that is farther away (i.e. outside of New Zealand) will not respond as quickly as a server that is located inside of New Zealand.

Internet Routing

We can't control how other networks send data to Vorco. For example this means if you are retrieving a file from Singapore, it might go the shortest route (Perth, Sydney, Auckland, you) or it might take a longer route (Japan, Los Angeles, Auckland, you). We do proactively monitor for instances where sub-optimal routing occurs and reach out to other networks to attempt to get them to reach Vorco via the most direct means but other networks ultimately decide how to route traffic back to Vorco.

Other Networks

The hosts or networks that you access on the Internet will have varying levels of performance, age and load.

Time of Day

Like roads, all networks have peak and off-peak times. We design Vorco's services to be able to deliver superior performance, but even if we're not experiencing congestion inside Vorco's network it does not mean that every other network along the way to the content you are accessing has the available bandwidth.

Factors inside Vorco's network

Our policy is that we invest in upgrading our network when any of our network links exceed 50% load. This is a level that ensures a very high standard of service to our customers. Short term congestion can still occur however and customers on broadband (burstable) services will have their packets dropped before customers on dedicated services. If high throughput is critical to your business then you should choose a dedicated service.

Factors inside the UFB network

The UFB network uses GPON technology. GPON supports 2.4Gbps downstream and 1.2Gbps upstream on each splitter. Splitters typically serve between 8-48 customers. As you can see, 3 customers on a splitter who are on Max (gigabit) plans would exceed the total available bandwidth and if they all wanted to utilise the full performance of their connection then they would not be able to do so. The available bandwidth would be shared equally instead.

Hyperfibre

Hyperfibre is an upgrade to the UFB network from GPON to XGS-PON technology. XGS-PON supports 10Gbps downstream and 10Gbps upstream on each splitter.

Important things to know about Hyperfibre

Hyperfibre is bleeding edge technology. We're enabling you to break the 1Gbps barrier on the Vorco network. It could take some years before everyone out on the internet catches up and can support the full Hyperfibre throughput.

All of Vorco's peering connections are a minimum of 10Gbps. Other parties on the internet commonly peer with 10Gbps interfaces but some only peer with 1Gbps. All providers' peering interfaces will likely be carrying traffic for many users, so you should not expect to achieve line rate throughput between yourself and every party on the internet, particularly on a single threaded connection.

Vorco peers openly at AKL-IX and MegaIX Auckland. You are most likely to achieve Hyperfibre speeds with other organisations who peer at these exchanges as well. Examples of cloud services at these exchanges are Microsoft, Amazon, Akamai, Netflix, Fastly, Cloudflare and lots of other New Zealand ISP's. Spark does not peer at these exchanges, and Vodafone only peer in a limited way at these exchanges, so you should not expect Hyperfibre throughput from Spark or Vodafone.

Hyperfibre is a best efforts broadband service, meaning your throughput will burst and fluctuate with network load both within Vorco's network and within other networks you are uploading to or downloading from.
