Factors inside your premises

Router/Modem

We strongly advise customers to use the router or modem provided with your service (if one was provided). We test these 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 Google Chrome version 55 or above, or the native Speedtest.net app in the Windows Store. We have observed poor Speedtest.net results in Mozilla Firefox and Apple Safari due to limitations in their Javascript engines.

WiFi

If you're using WiFi, this 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 the possible throughput will decrease as you move further away from the wireless router or access point, and because WiFi operates on unlicensed frequencies 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 is consuming 20Mbps, you will not exceed 80Mbps on Speedtest.net.

Internal Cabling/Switching

Older cabling in your office may not support Gigabit Ethernet. We recommend all internal cabling and switching is Gigabit Ethernet. If your internal network uses 10/100 switching then you will be unable to achieve more than approximately 80Mbps on Speedtest.net. 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 we cannot force the other network to do anything.

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 Business Class 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

CIR/EIR

All our plans come have a Committed Information Rate (CIR) and an Excess Information Rate (EIR). 

The CIR is the minimum amount of bandwidth that we guarantee you'll get through our network under a worst-case congestion scenario.

The EIR is the maximum amount of bandwidth that we allow you to use under a best-case scenario. 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.

It is possible you may only rarely reach the full EIR of your plan. This is particularly important to note on MAX (AKA Gigabit) plans. The current model UFB fibre network equipment is capable of a maximum of 2400Mbps download and 1200Mbps upload to each splitter. A splitter services between 8-48 customers. In a scenario where 48 customers all had chosen MAX (1000Mbps) plans, they would be sharing 2400Mbps and may rarely see the full MAX throughput. This instance is not a fault, and so MAX plans should be viewed as if the bandwidth is available, you can have it all as opposed to an artificial limit that a lower plan would provide.

The likelihood a customer would actually receive only their CIR and none of their EIR is incredibly unlikely, but this should factor into your choice about the right plan for you. If having high performance at all times is critical to your business then you should take a Business Premier or better plan.

Throughout the day your EIR or maximum speed will vary based on Vorco's network load as well as the above factors inside and outside your premises, like network load on the far end and WiFi performance on your end.
