Our broadband service is provided over a shared network. Bandwidth (the amount of data that can be transmitted on any one connection) is shared between everybody who's connected to the network.
We're constantly investing in our network, and so as customer numbers and usage grows, we increase the capacity of our network to make sure there's more than enough bandwidth for everyone.
In exceptional circumstances the network could become much busier than expected. This could be due to a major news event leading to a huge amount of online traffic, or in the rare case of network failure, for example. In these situations, we would prioritise traffic on our network to help ensure you get a great service no matter how busy it is.
