In 2006 roughly Tony Blair made it law that isp's had to keep the last 2 years of traffic data.
When Snowden came at the UK seemed to be scooping at the Atlantic lines everything it could and they had they're own search engine where they could scope out anyone in the network even to the point of turning people's camara's online without them knowing.

Most sites on the internet rely on 2048 bit wide composites made of 2 prime factors. It is considered to take to long for a computer to factorise such numbers this unproven assumption keeps the internet safe although the further development of quantum computers threatens this type of encryption called RSA.
However a few years ago the internet had to upgrade from 1024 bit encryption to 2048 bit due to a hack that was found and GCHQ use 10000 bit encryption if they even still use RSA encryption.
