Stanford University electrical engineer warns

Servers are packed with undetectable hardware flaws caused by the fact they have shrunk too much.

Stanford University electrical engineer Subhasish Mitra, who specializes in testing computer hardware said that as switches in computer chips have shrunk to the width of a few atoms, the reliability of chips has become another worry.

Companies like Amazon, Facebook, Twitter and many other sites have experienced surprising outages over the last year. The outages have had several causes, like programming mistakes and congestion on the networks. But there is growing anxiety that as cloud-computing networks have become larger and more complex, they are still dependent, at the most basic level, on computer chips that are now less reliable and, in some cases, less predictable.

Mitra warned about silent errors were coming from the underlying hardware made by various companies.
