# Service outage \(12/15/2021\) At approximately 10:40 AM EST Continu experienced a general service outage in the US-West-2 region. This outage resulted in customer instances becoming unreachable. Below is the chain of events that led to this outage and it’s resolution. * **10:40 AM EST** - The Continu Engineering team began receiving alerts that customer instances in the US-West-2 region began to show signs of degraded performance. The team spun a call up to begin troubleshooting and identified that all instances hosted in this region were slow to load or unreachable. * **10:45 AM EST** - During troubleshooting it became apparent that multiple other tools were unresponsive which is indicative of a much larger source issue unrelated directly to Continu. Reports of other services and sites hosted within out primary provider \(AWS\) becoming unusable began to surface. This coincided with an update to the AWS Global Service Dashboard that they were investigating internet connectivity issues. * **10:56 AM EST** - Continu customer instances begin to recover, service is restored to normal. * **11:01 AM EST** - AWS reports they have identified the root cause of their datacenter internet connectivity issues and begins to see early signs of recovery. * **11:14 AM EST** - AWS reports that their connectivity issues have been resolved and closes the incident. Continu concurs but continues to monitor recovery. The Statuspage incident is closed shortly thereafter. We at Continu thank you for your patience during this outage.
