Zen Internet: Unlike Other UK ISPs - We do not Shape Traffic

A post to Zen Internet's (UK) blog states that "All ISPs manage the data running across the network – the traffic – to some extent, but some larger ISPs are more intrusive. In some cases they throttle speeds, deliberately slowing down connections when users exceed what the ISP terms acceptable use. In others, they use a technique called Deep Packet Inspection to monitor usage and throttle the connection when you’re using specific bandwidth-intensive applications, such as Peer to Peer file-sharing.

.. At Zen, we think this is wrong. We don’t use traffic shaping or deep packet inspection in any form. We feel that our customers deserve services that are open, honest and easy to understand. That’s why our products use a fully transparent system of allowances, where customers simply pay for blocks of additional usage when they go over their generous monthly allocation, and where unused blocks can be held back for another month".

However, we understand that broadband usage patterns are changing. More of us are doing more online through more devices. That’s why we doubled the usage allowances across our product range and why we invest heavily in the network to ensure we can provide reliable speeds and quality of service.
