WebModern fault tolerance focuses on two kinds of faults, Byzantine Faults and Common Mode Faults Once every 400 days Justification For verification, older systems would have to prove that they had an error rate of 10-9 an hour. Assuming each hardware component had an error rate of 10-4 an hour, other faults would need to be around 10-5.
