What the heck is a Great NRH? January 12th, 2011: The earth is now in a different spot in relation to the sun than it has been for thousands of years, potentially changing your astrological sign. Nothing happens, but people panic anyway.

Did you hear about this? Probably not, so here it is… Google’s YouTube IPv6 traffic increased 30% last week. This intel comes to us from one of the world’s largest IPv6 ISP’s—the venerable Hurricane Electric in Fremont, Ca—whose own IPv6 traffic has already doubled this year.
