Did Stuxnet Take Out 1,000 Centrifuges At Natanz?

AffidavitDonda writes "In late 2009 or early 2010, Iran decommissioned and replaced about 1,000 IR-1 centrifuges in the Fuel Enrichment Plant (FEP) at Natanz, implying that these centrifuges broke. Iran's IR-1 centrifuges often break, yet this level of breakage exceeded expectations and occurred during an extended period of relatively poor centrifuge performance. Although Iran has not admitted that Stuxnet attacked the Natanz centrifuge plant, it has acknowledged that its nuclear sites were subject to cyber attacks."
