Last month's Google Cloud outage lasted nearly 22 hours, according to Computer Business Review. The outage occurred due to "a minor update to the Compute Engine API inadvertently changed the case-sensitivity of the 'sessionAffinity' enum variable in the target pool definition, and this variation was not covered by testing," Google wrote in an incident report.

3. Amazon Web Services

Amazon Web Services suffered an outage on Sept. 20. InformationWeek reported the outage affected Netflix, Buffer and other web companies.

5. Microsoft Azure
