Osano relies heavily on Amazon Web Services for all infrastructure. Cognito which is fault tolerant powers the authentication into the Osano dashboard experienced a major outage for approximately 6 hours.
Osano engineering confirmed that the errors were not due to Osano configuration issues but rather were caused by Cognito having an outage. The Cognito outage was the result of failures on a heavily used streaming component on Amazon called Kinesis. Kinesis had a global outage across many data centers that impacted AWS Cognito along with numerous other AWS services.
Outages of Kinesis on this scale are extremely rare and Cognito has had nearly 2 years without a single incident, so while this outage was inconvenient to customers, it is unlikely to recur and AWS has reassured us that mitigations are now in place to prevent this issue in the future.
