Technically this law covers logging at the ISP level for UK DSL and cable customers. However in reality, the UK is tapping all undersea cables coming into the UK (so basically almost all transatlantic ones), and logging everything. https://www.theguardian.com/uk/2013/jun/21/gchq-cables-secret-world-communications-nsa https://www.theguardian.com/uk/2013/jun/21/gchq-cables-secre.... This is done under the Tempora program: https://en.wikipedia.org/wiki/Tempora https://en.wikipedia.org/wiki/Tempora. So any connections into the UK are also being logged. This map gives you idea of the scale of connections coing through the UK: http://submarine-cable-map-2016.telegeography.com/ http://submarine-cable-map-2016.telegeography.com/ and this map shows the taps that have been discovered as part of the NSA Snowden leaks: http://lifewinning.com/submarine-cable-taps/ http://lifewinning.com/submarine-cable-taps/ (Source code: https://github.com/lifewinning/submarine-cable-taps https://github.com/lifewinning/submarine-cable-taps)
