This is an interesting lesson in disaster recovery planning for businesses using third-party datacenters for hosting. One common scenario is for a business with its own datacenter to use a private third-party datacenter (like the one in the article) as their off-site DR location. But what do you do when your DR location suffers an outage? Many companies will host in multiple datacenters to prevent outages in any one physical location from bringing down all of their operations. I suppose ultimate security could only be achieved using a distributed approach, but that may cost beyond what many businesses can afford (unless you are Google or Microsoft, for example).

But, in reality, uptime of servers at Amazon has been significantly lower than The Planet, even accounting for this outage. We have a couple of servers with The Planet, but luckily, they are in Dallas rather than Houston. This event did make me rethink our backup procedures, however. Backing up to another server in the same data center provides no protection against this kind of event, and though it sounds like there is no data loss, I'm sure a lot of folks were experiencing some pangs of regret yesterday before the full scope of the damage was understood.
- metachor 18y agoI think a minimal necessity for a DR plan is to have at least three geographically seperated hosting locations with some sort of automatic replication or fail-over. Again, this costs a lot of money. I don't know whether the ec2/cloud-computing is comparable as of today.
