One of the services we depend on had a brief outage that affected being able to do load PLIC Books and Elements. The outage lasted about 20 minutes and has since resolved on it's own. You can view more details about the outage at https://status.redislabs.com/incidents/h1gmlvw0g7v0. In the next weeks we will be taking steps to make our services more fault tolerant of errors such as these.
