There are three alert levels: low (24 h of autonomy or less), critical (1 h or less), then depleted. You are notified by e-mail (and by webhook if configured).
When the balance is depleted:
- running instances are destroyed (the local disk is lost);
- pending launches are cancelled;
- volumes are kept at first, with a deletion notice on day 5 and deletion on day 7 without a top-up.
To launch an instance, your available balance must cover at least 1 hour.
Advice: keep your balance topped up. For any question, contact support.
