// What happened

Trello’s official status page is reporting “Trello - degraded performance” with minor impact, affecting Trello.com and the API. Downrightnow’s current signals are otherwise quiet (no recent user reports or chatter), and Trello’s DNS is resolving normally, so this may be intermittent or only affecting some users rather than a broad outage.
