Warning levels
Warning levels tell you the balance is running out before any service stops. They give you four escalating chances to top up while everything is still running.
Warnings are measured against your recent spend, and an email is sent only when the balance crosses a threshold downward. All times use UTC+7.
Warning level 1
At Warning level 1, when your Credit drops below the equivalent of 12 hours of usage (0 < Credit < cost(12h)), service keeps running normally with no restrictions yet. You receive an email notification like the one below:

Warning level 2
At Warning level 2, when your Credit drops below the equivalent of 6 hours of usage (0 < Credit < cost(6h)), service keeps running normally with no restrictions. You receive a reminder email like the one below:

Warning level 3
At Warning level 3, when your Credit drops below the equivalent of 3 hours of usage (0 < Credit < cost(3h)), the system blocks new-resource creation to protect your account. You receive a high-priority email like the one below:

Warning level 4
At Warning level 4, when your Credit is below the equivalent of 1 hour of usage (0 < Credit < cost(1h)), the level 3 block on new-resource creation stays in place. You receive an urgent email like the one below:

At levels 3 and 4 you can still run, manage, and delete existing resources — only creating and scaling up new ones is paused.
When emails are sent
An email goes out only when the balance crosses a threshold, so you are not spammed for small movements within the same level:
- Balance keeps dropping into a lower level → you get that level's email.
- Balance rises into a higher level after a top-up → you get a "back to Warning" email for the new level.
- Balance moves but stays inside the same level → no email.
Sanction emails
Every email is sent to the customer, CC's the Account/Finance Manager, includes a Top up link, and is signed FPT Smart Cloud.

Recovering from a warning
Top-ups take effect immediately:
- Credit reaches ≥ 12h of usage → warnings reset, reminders stop, and any creation block is removed.
- Credit stays between 3h and 12h → the block is removed and the level is updated.
- Credit stays below 3h → the level 3/4 block remains until you top up further.
If the balance reaches 0, the account moves from Warning to Account Restricted.
