    Brief CLOB restart to roll out additional components as part of our ongoing latency-focused upgrades.

    Expected impact:

    • Intermittent trading for ~5-10 minutes. The CLOB will restart at 12:10 UTC.

    • Brief post-only window after restart (~2 min) before normal matching resumes.

    • Possible follow-up restart within ~1 hr of the initial window if needed.

    We'll update this page as the restart progresses.
