That gives Motorola about another 30 minutes before its self-imposed deadline. If it can't get the Moto Maker site back up and running by then, it has promised to double the supplies set aside for the deal, and run the deal two times. Motorola has scheduled the backup sale dates for noon EST on Wednesday December 4th, and again on Monday December 9th.
We'll keep an eye out, and update this article at 9:30PM EST with the final outcome of the sale. But, we're losing hope that Motorola will make its own deadline, so it may be a couple days before you can order your customized Moto X.
*Update* 9:30PM EST has come and gone and Moto Maker is still not working, so it looks like the Moto X sale will officially be scrapped for today and be held on December 4th and 9th.
