Dear Users,
This is a notice regarding the upcoming system maintenance to the Sandbox & Production environment. With this maintenance, 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 & Production Maintenance Window When: Saturday, August 22nd, 2026 Time: 7:00 AM ET to 10:00 AM ET Downtime: The Sandbox & Production environment may be unavailable for 30 minutes at the start of the maintenance window with increased latency or small periods of unavailability during the remaining time. Impact: During the maintenance windows, API connectivity and platform requests may experience brief intermittent errors or elevated latency while traffic is transitioned through upgraded infrastructure components. Once the maintenance is complete, all services will automatically resume normal operation. 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. Rationale: This maintenance window takes place during the period of lowest global trading activity. Action Required 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. For the most up-to-date information on this maintenance event, please refer to our Status Page and subscribe for updates. After 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.
Resolved -
On August 20, 2026, a subset of equity orders submitted during the early pre-market session were rejected between approximately 4:00 AM and 4:01 AM ET.
A configuration change applied ahead of the session caused the affected orders to be rejected at the time of submission. Rejected orders were not executed. Account balances, positions, and existing holdings were unaffected, and market data and all other platform services operated normally. Regular market hours trading was not impacted.
We identified the cause and reverted the change, and order processing returned to normal. Any affected orders can be resubmitted.
We are adding additional validation and monitoring for pre-market changes of this type and moving to a more gradual rollout process to reduce the likelihood of recurrence. We apologize for the disruption.

Between approximately 3:30 PM and 8:00 PM ET on August 19, 2026, some new users were intermittently unable to complete account registration due to maintenance work that caused sign-up attempts to time out. Existing accounts, live trading, order processing, and market data were unaffected throughout. The issue has been resolved, and anyone whose sign-up attempt failed during this period can now register successfully.
