US Patent 10223145 System for impairment issues of distributed hosts

A computing resources service provider may provide customers with access to virtual computing resources to execute various applications on behalf of the customer. There may be occasional impairment to the virtual computing resources. These impairments may be detected in log information obtained by an impairment detection service. Furthermore, the impairment detection service may obtain additional information associated with the virtual computing resources. The log information and additional information may be correlated to determine one or more relevant factors in the impairments.
