What is the difference between data methods?

We offer a variety of data methods to suit your needs. |
Block method is calculated on both Inbound (to your service) and Outbound (from your service) data usage. For example 25GB Inbound + 75GB Outbound is 100GB. Any data usage over the included quota is charged as an excess fee. This method suits best for those not knowing their requirements.
Paid in/Unlimited Out method is where data inbound to your service is charged, Outbound data is not calculated to usually a ratio limit. An example would be a ratio of 1:10 allowing 1GB in and up to 10GB Out. This method suits best for those with greater outbound requirements than inbound. (Also known as usage based).
Open Pipe method is where you have a certain sized connection. All data usage inbound and outbound within that pipe size is 'un-metered'. The benefit of this method is fixed known cost for bandwidth usage. Using the image of the 95th percentile graph below you can see the downside to this method, if you had an open pipe size of 2Mbps then any data beyond this threshold would result in 'flat lining' your connection.
95th Percentile/Burstable Billing:
95th Percentile method is similar to an open pipe however allows you to burst to higher throughput speeds if required. Billing is based on 95% of the usage with the top 5% of peaks being discarded.
In the below example the 95th percentile is 1.85Mbit per second with the top 5% of peaks being removed.
