    Brief CLOB restart to roll out additional components.


    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 the status page as the restart progresses.
