The weeks long connection troubles many Xbox Live users have experienced since the holidays was due, according to Microsoft, to heavy Xbox Live server load brought on a record number of users attempting to access the service. Xbox group marketing manager Albert Penello told Kotaku that "It's wasn't a malicious thing." He explained, "We had the biggest concurrent day we've ever had on Live. We had more people than ever signing up on Live, it was 9 million, then 10 million, and it literally was that a lot more people were trying to get on, sign up and play than we had expected over Christmas."
Penello gave further explanation for the continued problems and defended the Live team.
