End-to-end encryption doesn't mean that your iMessages are secure enough to hide your trace because Apple not only stores a lot of information about your iMessages that could reveal your contacts and location, but even share that information with law enforcement via court orders.

Yet despite their emergence as nerve centres of the global economy, data centres have drawn almost no attention in debates about globalisation and nor are they often discussed outside of business and IT publications.

Piotrowicz said that the data regarding changes in temperature and salt levels being recorded at deep sea levels are important in understanding sea level rise but was very limited.
