HTTPS port 443

Only if you restrict outbound SSL connections via the standard port 443, please unblock the Box's access to the following servers:

1. https://camio.com
2. https://*.camio.com
   
   The following URLs are currently used but they will soon be replaced by CNAMEs on the camio.com domain (so covered by #2 above at that point). For now, allow access also to:
3. https://camio-cameras.appspot.com
4. https://cam-dot-camiologger.appspot.com
5. https://cam-dot-camio-test.appspot.com
6. https://camiologger.appspot.com
7. https://praxis-api-dot-camio-test. appspot.com
   
   The following URLs are used while managing packages on the system, for DNS inquiries, and for managing the NTP daemon.
8. https://files.pythonhosted.com
9. https://pypi.org

HTTP port 80 (only to fix clock drift)

Only if SSL fails due to severe clock drift on the Box, a single HTTP request for the current time via port 80 is made to this server. All external communications are SSL encrypted other than this rare HTTP request used only to correct the local clock:

10. http://camio.com/time

NTP Servers

Box used Ubuntu's NTP servers (port 123)

11. ubuntu.pool.ntp.org

DNS Servers

The Box uses Google DNS servers by default:

12. 8.8.8.8
13. 8.8.4.4
