On February 18-19, Google Compute Engine went down for two hours and forty minutes. The company said that the problem, which began around 11 p.m. Pacific Time on Wednesday, resulted from a glitch in the cloud computing service's internal software..
Google explained, "The issue manifested as a loss of external connectivity to the instances, and an inability of the instances to send traffic outside their private network. The instances themselves continued to run, and became available again as their external traffic loss cleared."
According to CloudHarmony, Google Compute Engine experienced 72 outages with a total of 4.42 hours of downtime in 2014.
