AI Generation

  1. Resolved · 16:35 UTC

    Generation times are back to normal and the backlog has cleared. Every set queued during the incident finished — nothing was lost.

  2. Monitoring · 15:20 UTC

    We added capacity to the generation queue and times are falling. Sets already in the queue are still processing in order.

  3. Identified · 14:25 UTC

    A backlog in the generation queue is delaying new sets. Study, decks and everything else are unaffected.

We publish this page by hand rather than from automated monitoring, so it reflects what we know at the time of the last review. If ClassFactor is not working for you and this page says everything is fine, please tell us — that is genuinely how we find out about some of them.
