What was the point of signing up for pre-order emails and following your launch if it was going to be announced everywhere at the same time? Your website is down and it was impossible to complete a pre-order checkout because of all the errors.
Sorry for the go-live shakiness. The website is up and running solidly now. We sent out the email to the mailing list this morning with the intent of letting folks get in and order as the news started to trickle out. In reality though, there was an immediate, massive influx of traffic (in part from HN) that brought down the website. Lessons learned for the future.
