Newsgator outage explained

I posted about NewsGator’s outage on my personal blog, and got a comment pointing me toward the official explanation. If you’re interested in messaging and collaboration HA, it’s worth a read. The money quote:

Frankly, this was a pretty frustrating experience. We have a lot of redundant systems – pretty much any piece of hardware in our data center could fail, and we can absorb it without a significant outage. For example, if an entire SQL box would have lost power, fallen on the floor, and broken into pieces, no problem, we’d have an approximately 10 second outage. But this case, where the database gets into an inconsistent state, wasn’t helped by the redundant systems.
