# Scheduled upgrade and maintenance periods Phocas regularly performs scheduled maintenance to keep our system in top shape. This is typically one of the following types of maintenance: * **System maintenance** such as security patching, to support the availability, stability and performance of the infrastructure behind Phocas * **Upgrades** releasing the latest version of Phocas to customers, to provide new or enhanced features and functionality and bug fixes. During periods of scheduled maintenance Phocas is temporarily unavailable. We endeavour to keep the impact of this maintenance to a minimum and in most cases you may only experience a brief disruption. Please refer to our [status page](https://status.phocassoftware.com/) for details on upcoming scheduled upgrade and maintenance periods. If you have any questions please contact your Phocas Account Manager. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
