If you visited Nintendo World Report over the weekend you might have noticed that the site had mysteriously disappeared. We're back up now, but it was a frustrating weekend for us. We learned that our database hosting provider, located in Houston, Texas, experienced a major outage. "Major," in that a major electrical component shorted out, creating an explosion big enough to knock down three walls surrounding the room in which it happened.
The subsequent fire forced our host to shut down the entire data center, affecting 9,000 servers. Thankfully, no one was hurt in the incident and no one lost any data. NWR was never in any real danger of being lost to the Internet, as we redundantly back up our servers onto each other in case freak accidents like this happen.
It appears that our physical server was none the worse for wear, and once our host resolves its power issues as a result of damage to the building, we should be just fine. However, we were quite lucky to be located on the second floor of the building, as the first floor suffered major damage to networking and power systems significant enough for them to be knocked out of commission for at least the rest of the week. If our server was down on that level, we may not have been around for quite some time!
That's the explanation about our downtime. We apologize for not being here, even it was completely out of our control.
