Apparently it ended on the 27th.
World of Warcraft's record-setting first week brought hundreds of thousands of players together to adventure in Azeroth. The extremely high concurrency numbers that we've seen since the game's launch have required us to double our total number of servers over a four-day period, which is much faster than we had initially planned. This caused some issues with a few servers, and some players had difficulty logging in to the game during this period.
We are determined to provide our players with the best experience possible. It is for that reason that we are extending the one-month trial-period for players who created accounts before or during the downtime. The length of the trial-period extension will be based on when the player's account was created:
Accounts created on November 23 will receive a 4-day extension
Accounts created on November 24 will receive a 3-day extension
Accounts created on November 25 will receive a 2-day extension
Accounts created on November 26 will receive a 1-day extension
Our sincere apologies go out to all who experienced service disruptions. As always, we appreciate your patience and support, and we wish you good luck in your adventures in Azeroth!
It was a nice gesture, but not that nice.

Blizzard is obviously thrilled by the World of Warcraft success as sales numbers show WoW has broken day-one sales records in North America. World of Warcraft sold over 240,000 copies at retailers in North America on Tuesday, November 23, selling more in its first 24 hours than any other PC game in history.
Within the first day, over 200,000 players created World of Warcraft accounts, and over 100,000 were playing the game simultaneously, quickly filling all original 40+ World of Warcraft servers. This created some frustration with a lot of people wanting to play but instead experiencing long wait times or annoying lag, so Blizzard quickly scrambled together an additional 40 servers to meet the demand.
