Broadband data traffic on TalkTalk's network has almost trebled in three years, the service provider has claimed.
Traffic has peaked at over 1Tbps in 2014 and regularly reaches 990Gbps, the firm has revealed. January's peak of 900Gbps was significantly up on the 557Gbps reported 12 months earlier.
Colin Whitbread, Chief Network Officer at TalkTalk, said the firm's network is "getting bigger, faster and smarter to keep up with the unprecedented increase in demand for bandwidth".
"Traffic on our network has almost trebled during the last three years, with huge spikes during key events like the launch of Apple’s iOS7 or big TV events like the 2012 Olympics," he stated.
Mr Whitbread said TalkTalk's decision in 2013 to make all broadband packages totally unlimited - with no caps on usage or traffic management - has contributed to customers feeling free to download as much as they like.
TalkTalk homes currently download an average of 34GB of data a month, 46 per cent more than a year ago and 22 per cent more than three months ago.
Mr Whitbread described this as "phenomenal growth".
"The network will continue to accelerate in coming years as customers use ever more gadgets that connect to the web, stream TV services like YouView from TalkTalk, and of course continue to make billions of voice calls," he predicted.
Mr Whitbread said TalkTalk will be "continually investing" to increase network capacity over the next five years, ensuring there is more than enough bandwidth to meet demand.
"We are also planning extra capacity according to our customers’ growth trends and forecasts to ensure we are always one step ahead and avoid any congestion," he added.
At the same time, the broadband provider is improving resilience, meaning that if problems arise in one part of the network, traffic can be rerouted without causing issues for customers trying to get online.
"Many people now think of broadband as a utility, just like electricity and water," Mr Whitbread stated.
"So it is more important than ever our customers know they can rely on TalkTalk."
