Alpaca incident

Temporary order rejections

Resolved on August 27, 2026, affecting Orders API.

resolved Aug 27, 2026, 09:28 AM UTC

We experienced a brief period of order rejections caused by an upstream venue rate limit being exceeded during a short burst of order traffic. The issue lasted approximately two seconds and has since stabilized. Orders are now processing normally. We are reviewing follow-up improvements to reduce the likelihood of similar rate-limit events.
