Lightning in Dublin knocked out Amazon and Microsoft Data Centers, reports Data Center Knowledge. Amazon said that lightning struck a transformer near its data center, causing an explosion and fire that knocked out utility service and left it unable to start its generators. Microsoft said that the Dublin data center’s utility power was similarly struck by lightning with power restored at 03:10 AM PST Monday and the data center “has returned to normal operating conditions.”
Amazon.com’s EC2 cloud service also suffered another outage this evening, taking out several high-trafficked Web sites, including Instagram, Quora, Foursquare and other sites. Amazon’s Elastic Compute Cloud (EC2), facility in northern Virginia appeared to be the source of that problem.
Dublin has become a key cloud computing gateway to Europe and beyond for U.S. companies. Microsoft built one of the world’s most efficient data centers in Dublin, a huge facility that hosts the company’s cloud services for Europe and operates entirely without chillers. At 550,000 square feet, it is also one of the world’s largest data centers.
Microsoft’s video offers “a deeper look at how Microsoft uses secure, reliable, scalable and efficient best practices to deliver over 200 cloud services to more than a billion customers and 20 million businesses in over 70 countries.”
Originally developed to house the printing presses for the Sears Catalog, the building was converted to telecom use in 1999, and today it is the nerve center for Chicago’s commodity markets, housing data centers for financial firms attracted by the peering and connectivity providers among the 70 tenants.
Three electric power feeds provide the building with more than 100 megawatts of power.
