To ensure that it is always available to you, its health is monitored continuously, and its regular maintenance is rigorously performed. When your cloud server requires maintenance or a hardware or software upgrade, it might be necessary to interrupt your AngelTrack service. Such interruptions are scheduled to occur during specific windows of time, so as to minimize the impact on your operation and help you plan for (or avoid) them. #### Examples of maintenance During a maintenance window, we perform the following types of maintenance on your AngelTrack cloud server: - Apply operating system patches, which usually require a reboot - Deploy a regular AngelTrack upgrade (refer to [the list of AngelTrack releases](https://angeltrack.com/releases/) to see what is included in these upgrades) - Perform database optimizations such as index defrag - Migrate your cloud server to a different blade No action is required from you during these procedures; it is always handled for you by AngelTrack staff members who are dedicated with uptime. #### Technical support is still available during this time We promise 24/7/365 phone technical support, and that includes maintenance window hours. We are always here, should you need us. ### Weekly Maintenance Window Each week there is a two-hour maintenance window, opening **early Sunday morning at 02:00 US Central Standard Time**. During this window, your AngelTrack cloud server may become temporarily unavailable, if a restart is required to complete a software or hardware upgrade. If your work cannot be postponed, then save often. That two hours is the period in which AngelTrack *might* be unavailable, not that it *will* be unavailable. Normally the weekly update causes just a few minutes' interruption. When a maintenance window is approaching, all AngelTrack pages turn their top-ribbons orange, and display a blinking warning message: ![MaintenanceWindow.approaching](https://support.angeltrack.com/hs-fs/hubfs/Imported%20images/MaintenanceWindow.approaching.png?width=500&name=MaintenanceWindow.approaching.png) The warning turns from orange to red when the maintenance window is actually open. Keep in mind, just because the cloud server *could* become temporarily unavailable doesn't mean it *will*. AngelTrack technicians always endeavor to perform upgrades and maintenance *without* interrupting service; a service interruption is done only when absolutely necessary. ### Updates, New Features, and Fixes To learn what features and fixes are in the latest update, or were in prior updates, please visit the [AngelTrack Release Notes site](https://angeltrack.com/releases/). We ship a new update about twice a month. We take care of all the chores of applying it to your AngelTrack server; you do not need to do anything to always receive the latest update as soon as it gets released. - [General Topics](https://support.angeltrack.com/help/general-topics?hsLang=en#main-content) - [Configuration](https://support.angeltrack.com/help/general-topics?hsLang=en#configuration) - [Integrations](https://support.angeltrack.com/help/general-topics?hsLang=en#integrations) - [State and County Uploads](https://support.angeltrack.com/help/general-topics?hsLang=en#state-and-county-uploads) - [Dispatch](https://support.angeltrack.com/help/dispatch?hsLang=en#main-content) - [Basic Dispatch](https://support.angeltrack.com/help/dispatch?hsLang=en#basic-dispatch) - [Schedules and Recurrences](https://support.angeltrack.com/help/dispatch?hsLang=en#schedules-and-recurrences) - [Connections to Billing](https://support.angeltrack.com/help/dispatch?hsLang=en#connections-to-billing) - [Advanced Topics and Tips](https://support.angeltrack.com/help/dispatch?hsLang=en#advanced-topics-and-tips) - [Vertex AI Dispatch Planner](https://support.angeltrack.com/help/dispatch?hsLang=en#vertex-ai-dispatch-planner) - [Supervisors](https://support.angeltrack.com/help/supervisors?hsLang=en#main-content) - [Fleet](https://support.angeltrack.com/help/supervisors?hsLang=en#fleet) - [Compliance](https://support.angeltrack.com/help/supervisors?hsLang=en#compliance) - [Billing](https://support.angeltrack.com/help/billing?hsLang=en#main-content) - [Invoicing](https://support.angeltrack.com/help/billing?hsLang=en#invoicing) - [Pricing and Contracts](https://support.angeltrack.com/help/billing?hsLang=en#pricing-and-contracts) - [Coding, Claims, and Clearinghouse](https://support.angeltrack.com/help/billing?hsLang=en#coding-claims-and-clearinghouse) - [Prior Authorization and PCS](https://support.angeltrack.com/help/billing?hsLang=en#prior-authorization-and-pcs) - [Billing Workflow](https://support.angeltrack.com/help/billing?hsLang=en#billing-workflow) - [Payments and EOBs](https://support.angeltrack.com/help/billing?hsLang=en#payments-and-eobs) - [Facility and Patient Records](https://support.angeltrack.com/help/billing?hsLang=en#facility-and-patient-records) - [QA Review](https://support.angeltrack.com/help/qa-review?hsLang=en) - [Salesperson](https://support.angeltrack.com/help/salesperson?hsLang=en) - [Human Resources](https://support.angeltrack.com/help/human-resources?hsLang=en#main-content) - [Timeclock](https://support.angeltrack.com/help/human-resources?hsLang=en#timeclock) - [Schedules and Vacations](https://support.angeltrack.com/help/human-resources?hsLang=en#schedules-and-vacations) - [Crew Members](https://support.angeltrack.com/help/crew-members?hsLang=en#main-content) - [Report Completion](https://support.angeltrack.com/help/crew-members?hsLang=en#report-completion) - [Documents](https://support.angeltrack.com/help/crew-members?hsLang=en#documents) - [Fire](https://support.angeltrack.com/help/fire?hsLang=en) - [IT](https://support.angeltrack.com/help/it?hsLang=en#main-content) - [Data Protection](https://support.angeltrack.com/help/it?hsLang=en#data-protection) - [Troubleshooting](https://support.angeltrack.com/help/it?hsLang=en#troubleshooting) - [Miscellaneous](https://support.angeltrack.com/help/miscellaneous?hsLang=en#main-content) - [Articles for patients and facilities](https://support.angeltrack.com/help/miscellaneous?hsLang=en#articles-for-patients-and-facilities) - [Report Builder](https://support.angeltrack.com/help/report-builder?hsLang=en#main-content) - [Walkthroughs](https://support.angeltrack.com/help/report-builder?hsLang=en#walkthroughs) - [Built-In Reports](https://support.angeltrack.com/help/report-builder?hsLang=en#built-in-reports) [![Chill listening crop-3](https://support.angeltrack.com/hs-fs/hubfs/A.400x400.png?width=40&height=40&name=A.400x400.png "Chill listening crop-3")](https://support.angeltrack.com/help/index.htm?hsLang=en) AngelTrack Support Home Copyright © 2026, AngelTrack LLC
