Crisis Management During Sandy

The news this past week has brought endless images of devastation. All metropolitan region, the damage is apparent.

More than once in conversation I’ve commented “That’s similar to what I do.” The response is often one of confusion. So I go on to clarify. Web operations is every bit about disaster recovery and crisis management in the datacenter. If you saw Con Edison down in the trenches you might not know how that power gets to your building, or what all those pipes down there do, but you know when it’s out! You know when something is out of order.

That’s why …
