On September 13, 2022, at 20:49 UTC, customers in the Sydney data center experienced networking interruptions to Block Storage and LKE. Our internal monitors alerted administrators about the outage, and Linode's incident response procedures were initiated as of 20:53 UTC. Customers would not have been able to access these resources during the incident.
The outage resulted from updates to networking switches inside the data center. Networking connectivity and access to Block Storage and LKE services was restored as of 21:20 UTC, and the incident was considered fully resolved as of 23:31 UTC.
As a result, we have implemented additional safety checks to our update process. This will ensure that networking hardware is not in production when updates occur.
