Here's a list of interesting articles dealing with the data center and cabling.
Cabling Install and Maintenance recently published this story: 70% of data center outages directly attributable to human error. I started thinking about the costs of unplanned downtime in the data center. I didn’t have to look far to find some really good examples of this:
Amazon.com suffered an outage on Monday August 19th. The estimated cost of the site being down 40 minutes is $4.72 million in lost sales!
Apple iCloud went offline on August 22nd. There are estimates of 1% of users being affected by this blackout. With a customer base of more than 300 million users that translates to 3 million people being affected!
Endurance International Group, which operates a data center in Provo, Utah, had an unplanned network outage as well. Millions of websites and email systems were affected during the Major Outage for BlueHost, HostGator, HostMonster.
It turns out the problem was slight hydraulic movement of the transport erector launcher that raises and supports the rocket, coupled with insufficient slack in the cord to account the unplanned movement. The company says neither issue alone would have caused the umbilical disconnect, but “the combination resulted in the anomaly.” It is easily fixed by adjusting the apparatus that supports the rocket before launch.
Possible causes related to human error could include disconnecting a jumper or power cord, failing to perform a check, and errors in judgment.
Now I’m not saying that human error attributed to any of these unplanned outages – but……what if?
