while phone number is unique at any given moment, it doesnt necessarily mean it stays with same person. Most providers sell the used numbers some time after they got inactive.
Good luck to the new buyer of 1000 ranked number
When I moved to the US, I bought a T-Mobile SIM. A month later, I started receiving robo calls from a debt collector. After about 10 of those calls I finally gave in and called them back on their 800 number and they gave me the name of some guy they were looking for. Probably the previous owner of the number...
This is how the "40%" looked in real life: http://www.crackajack.de/2013/08/18/google-goes-down-for-2-minutes-fucks-up-100-of-all-journalists/
(Mind the circle in the yellow graphics: It shows the real decline in internet traffic at the German Internet Exchange (DE-CIX), the largest internet exchange point worldwide.)

The vast majority of Google traffic bypasses internet exchanges and is carried directly between ISPs and Google.
Hardly radical. Power stations have done it for years, some other food processing factories have used the heat to warm up greenhouses to grow tomatoes.
A radical idea would be putting data centers in a cooler climate so they can be cooled more with ambient temperatures.
For example like Google's Hamina data center? http://www.google.com/datacenter/hamina/
If you put a SIM card into your 3G phone, then it is GSM. The term 3G has become little more than marketing rubbish at this point.
That is incorrect. 3G is UMTS, but can seamlessly hand over calls to the 2G GSM.
Anything free is worth what you pay for it.
