Just a few weeks ago we reported that Facebook was growing by 600,000 users a day. If that wasn’t enough, CNET reports that Facebook set record traffic numbers on Christmas Eve.

During the month of November, Facebook was averaging 1.42% of all U.S. Internet traffic. On December 24, they hit a Facebook-best 2.18% market share that day. That’s a 54 percent increase over November average and a 53 percent increase year over year. Needless to say, things are going well for them.

According to CNET, that pattern was mirrored in the U.K., where visits to the social networking site had a market share of 4.65 percent, accounting for one in every 22 Internet visits.

As for what is causing this strong traffic increase, Heather Hopkins of Hitwise theorizes it was a combination of boredom and bad weather. Facebook’s primary markets (New York, Chicago, Washington, Boston, and Philadelphia) were all slammed with bad weather.
