Scheduled Maintenance
Maintenance in Sandbox Today ( 21st May 2026) @ 6pm-8pm - EDT May 21, 2026 18:00-20:00 EDT
Dear Users,
This is a notice regarding the upcoming system maintenance to the Sandbox environment. Our goal is to accelerate the release of system fixes and improvements, ensuring you and your users benefit from a more stable and enhanced product more quickly.
Sandbox Maintenance Window
When: Thursday, May 21st, 2026
Time: 6 PM to 8 PM ET
Downtime: The Sandbox environment may be unavailable for up to 2 hours. Please note that maintenance windows are approximate. While we aim to complete work within the scheduled timeframe, maintenance may conclude earlier or occasionally extend if additional work is required to ensure system stability.
Once maintenance is complete (or if no maintenance was required), Alpaca will issue an "Scheduled Maintenance Complete" status update after the window has passed
Rationale: This maintenance window takes place during the period of lowest global trading activity.
Action Required
Partner Action: No action is required from you at this time and there will be no impact to Production environments. We simply ask that you are aware of this scheduled window and prepare your internal teams for the possibility of a brief downtime.
Recommendation: Please ensure your internal teams are aware of this scheduled window to account for the possibility of a brief outage that could temporarily affect all services, including deposits and withdrawals.
After the Maintenance:
No action is required on your part following the maintenance. All API endpoints, credentials, and integration configurations will remain unchanged.
We are committed to continuous improvement, and this process change will help us deliver stability and enhancements with greater speed.
If you have any questions or require further clarification, please reach out to your Customer Success Manager or our support team at brokersupport@alpaca.markets.
Best Regards,
Alpaca Team
