A small number of users are running into page errors when trying to access Canvas. This is the result of a DNS issue from Amazon Web Services (AWS).

Although this has since been resolved, some users using specific Internet Service Providers (ISP's) may still be impacted. If you're continuing to see the behavior, resetting the network connection may help remedy the errors. We will monitor the situation and post further updates as they become available.
