Why does Tails automatically connect to several websites when starting?
-----------------------------------------------------------------------
Tor and I2P require the system clock to be well synchronized in order to work
properly. When starting Tails, a notification is displayed while the clock is
being synchronized.
This synchronization is made by sending HTTPS queries through Tor to severals
websites and deducing a correct time from their answers. The list of websites
that could be queried in this process can be found in `/etc/default/htpdate`.
