    We will be performing scheduled maintenance to deploy a CLOB release and migrate the Gamma database.
    Expected impact:

    • Trading paused for ~10–15 minutes. The CLOB will restart at 12:10 UTC

    • ~2 minutes of cancel-only + post-only mode after restart. Cancels and orders with postOnly: true will be accepted; market orders and taking liquidity will be rejected. Normal matching resumes after the window See API Reference.

    • New user signups and comment posting will be unavailable during the window.

    • Market browsing continues to work. Sports markets data (volume, live scores) may appear stale for ~10 minutes.

    This migration moves Gamma from RDS to Aurora, providing faster reads, lower replica lag, and additional scaling headroom to support upcoming product work.

    The CLOB will enter cancel-only mode at 16:30 UTC, followed by a restart at 16:35 UTC (~5 minutes of downtime). Cancel-only mode will continue until 16:45 UTC, after which full trading resumes.

    During cancel-only mode, no new orders can be posted, only cancels. We'll update this page once maintenance is complete.
