Systems and methods for accessing an update server to receive one or more updates for data are provided. In some aspects, a system includes an auto-update module configured to determine whether to access the update server directly or by proxy. If the auto-update module determines to access the update server by proxy, the auto-update module is configured to: transmit a request to a proxy manager module for proxy server data that identifies one or more proxy servers; receive the proxy server data from the proxy manager module in response to the request; and access the update server based on the proxy server data to receive one or more updates for the data. The auto-update module is subject to fewer restrictions in modifying the data than is the proxy manager module.
