Back in "the day," Alexa was a very talked about tool for checking the traffic data for a third party site. These days, people know to take Alexa's data with a grain of salt. Alexa data can be easily spoofed and tampered with, at least - that is what I am told, so just be careful when using it.
That being said, DigitalPoint Forums has a large discussion on Alexa. They claim it has just updated their numbers.
Scanning the thread, it seems like most webmasters are happy with the new results. One said:
Both of my sites had a massive 1000% change as of the Alexa update.
Again, be careful when using this data.
