CDN billing
Current CDN pricing is available on the pricing page.
Billing plans and overage
Each plan has a one-month traffic limit and a request limit. When traffic or the number of requests exceeds the plan limit, additional charges apply.
| Monthly traffic limit | Traffic overage | Request overage | |
|---|---|---|---|
| Description | The amount of traffic available within the plan. Includes traffic from the origin to a CDN server and from a CDN server to an end user. Resets on the 1st day of each calendar month | Amount of traffic used over the plan limit | The number of requests made over the plan limit. Includes requests from an end user to a CDN server and from a CDN server to an origin |
| Billing | The plan fee is charged on the 2nd day of every month | CDB charges overage in portions of €50 or $60 (currency depends on account settings). Traffic and request overage costs are combined. As soon as accrued expenses reach €50 or $60, that amount is charged | |
| Example | The plan fee is charged on the 2nd day of the month | The plan allows 5 TB of traffic and 1 billion requests. If the limit is reached and CDN use continues, CDB calculates the combined cost of traffic and request overage. The account is charged once accrued expenses reach €50 or $60 |
Plan fees are prorated when a plan is activated mid-month. Activating a €100/month plan on September 15 — with 15 days remaining — results in an initial charge of €50. On October 2, the full €100 is charged for the entire month.
Overage is charged in portions of €50 or $60 because this is the credit limit — the maximum value of unpaid costs. The CDN keeps working as long as overage charges stay below the credit limit. Unpaid costs below the credit limit are charged on the 2nd day of the following month together with the plan fee.
Assume the plan costs €100/month and the credit limit is €50. The traffic limit is reached mid-month. The extra traffic rate is €0.02/GB. By the end of the month, 100 GB of extra traffic has been used — €2 in overage. Since €2 does not exceed the €50 credit limit, it is charged next month: the total charge is €102 instead of the regular €100.
The credit limit shown above is illustrative. The actual limit is visible in the account Dashboard.
Service suspension for non-payment
Once overage costs reach the credit limit, CDB charges that amount from the account. If payment fails, the linked payment instrument (a credit card added at signup) is charged automatically. If payment fails again, the CDN stops delivering content. Recharge the account manually — CDB charges the unpaid costs and reactivates the services. The credit limit renews and the CDN keeps running until the credit limit is reached again.
If on the 2nd day of a month the account balance is insufficient to cover services, two scenarios apply:
- No unpaid costs from the previous month: CDB charges the account for the plan fee and additional options. If payment fails, the linked payment instrument is charged. If that also fails, CDB retries on the 3rd and 4th of the month. If payment fails on the 5th, all active services — CDN, Object Storage — are suspended.
- Unpaid costs from the previous month: CDB charges the unpaid costs first, then the plan fee and additional options. If payment fails, the linked payment instrument is charged. If that also fails, all active services — CDN, Object Storage — are immediately suspended.
