Online password keeping service LastPass.com reports that it is possible that they were 0wned. (how nice!) In the same time, PastPass seems to be doing the right things: they had a monitoring in place, so they have detected an anomaly in traffic. As soon as the anomaly was detected, they have notified their users and proceeded with further measures.

Postmortem for the April-2011 EC2/EBS outage. It looks like a human errors plus unfortunate cascade of events lead to a requests storm that brought down EBS storage. Also, it appears that Amazon mis-estimated spare storage capacity needed for recovery from such events.

"The history of every major tech startup tends to pass through three distinct and recognizable phases, those of Survival, Inquiry and Sophistication, otherwise known as the How, Why and Where phases.
For instance, the first phase is characterized by the question "How can we make payroll?", the second by the question "Why do we need VC?", and the third by the question "Where shall we have lunch?"
It should be the goal of every startup company to reach the third stage."
