VMRack CDN adopts a simple and transparent Pay-As-You-Go billing model, coupled with a monthly free quota, making every penny of your investment clear and visible. This chapter uses practical cases to help you understand the billing logic.
PayAsYouGo:
No upfront fees required. The system generates bills based on your actual usage volume and automatically deducts the amount from your Account Credit.
Hourly Settlement
The billing cycle is 1 hour. The system settles the bill for the previous hour (09:00:00-09:59:59) at every whole hour (e.g., 10:00:00).
1.Billing Precision: The bill amount generated each hour is accurate to 4 decimal places (e.g., $0.5188).
2.Actual Deduction: Deductions are executed only to the 2nd decimal place ("cents").
3.Unsettled Amount: The 3rd and 4th decimal places (the part less than 1 cent) are not deducted temporarily but are automatically calculated into your "Unsettled Amount".
Monthly Unified Settlement: The system performs a "Summary Settlement" of all "Unsettled Amounts" from the previous month on the 1st of each month.
Summary Calculation
Sums up the unsettled balances generated from all hourly bills in the previous month.
Final Deduction
The summarized total is rounded to 2 decimal places for a one-time deduction.
Waived Amount
If the summarized result still has remainders in the 3rd or 4th decimal places, the system directly waives (writes off) this amount, and no payment is required.
To ensure fairness and transparency in billing, we follow these standards:
Metering Unit: Traffic is billed in GB (1GB = 1024MB).
To lower the barrier to entry for users, VMRack provides a monthly free traffic quota for all users.
1.Gifted Quota: 30GB traffic per month.
2.Refresh Mechanism: The quota automatically refreshes at 0:00 on the 1st of each calendar month. Unused quota from the previous month cannot be rolled over to the next month.
3.Deduction Rule: The free quota is prioritized for deduction during settlement; billing starts for the excess part only after the free quota is exhausted.
To help you understand the logic of free quota deduction and hourly settlement, we simulate a user (User A) starting the service on January 1st.
Scenario Setup
User Rights: Has 30GB of monthly free traffic.
Assumed Price: $ 0.0200 / GB (Note: This price is for example only; please refer to the system for actual pricing.)
Usage Record
User A performed the following operations on the morning of January 1st:
09:00:00 ~ 09:59:59 : Website traffic spike, generated 20 GB traffic.
10:00:00 ~ 10:59:59 : Traffic continued, generated another 15 GB traffic.
11:00:00 ~ 11:59:59 : Business stable, generated 5555 MB traffic.
Cost Breakdown
Time Period | Actual Usage | Free Quota Deducted | Billable Volume | Explanation | Amount (USD) |
09:00:00 ~ 09:59:59 | 20 GB | 20 GB | 0 GB | Full Deduction. Free quota remaining this month: 30 - 20 = 10 GB | $ 0.0000 |
10:00:00 ~ 10:59:59 | 15.6 GB | 10 GB | 5.6 GB | Partial Deduction. • Prioritize deducting remaining free quota 10 GB, free quota exhausted. • Billable traffic: 15.6 - 10 = 5.6 GB • Fee: 5.6 GB * $0.0200/GB = $ 0.1120 | $ 0.1120 |
11:00:00 ~ 11:59:59 | 955 MB | 0 GB | 955 MB | Full Billing. • Convert GB: 5555MB / 1024 ≈ 0.9326 GB} • Fee: 0.9326 GB * $0.0200/GB ≈ $ 0.0186 | $ 0.0186 |
Bill Analysis
Billing Cycle | Bill Amount | Paid Amount | Unsettled Amount |
09:00:00 ~ 09:59:59 | $0.0000 | $ 0.00 | $ 0.0000 |
10:00:00 ~ 10:59:59 | $0.1120 | $ 0.11 | $ 0.0020 |
11:00:00 ~ 11:59:59 | $0.0186 | $ 0.01 | $ 0.0086 |
Monthly Settlement
Assuming User A only has the above transactions this month, on the 1st of the next month, the system will process the accumulated unsettled amounts:
Total Unsettled Amount: $0.0020 + $0.0086 = $0.0106.
Actual Deduction: The summarized amount exceeds 1 cent, system deducts $0.01.
Waived Amount: The remaining remainder of $0.0006 is directly waived, and the user does not need to pay it.
Note: The above traffic fees are example data to simplify the explanation of billing rules. Please refer to the system for actual unit prices!
Bills are typically generated one hour after the end of the current billing cycle. The specific issuance time is subject to system processing. Inquiry method:
Log in to the console, pull down the Avatar menu in the top right, and select Billing.
In the left navigation bar, select Pay-As-You-Go Bill to view detailed statements and billing charges.
When the account credit is less than $20.00, the platform will send message and email notifications to remind you. To avoid service unavailability caused by arrears, please pay attention to the account credit consumption and ensure sufficient account credit.
On the Credit page, you can configure the alert settings and threshold for credit warnings.
Please pay close attention to your account credit status to avoid business impact caused by arrears.
Arrears Trigger
When the system detects that your account credit is insufficient to pay the current bill (Account Credit < 0), the service will enter an arrears state.
Suspension Handling
The system will automatically stop CDN acceleration services for all sites under the account.
You will be unable to access the CDN Control Panel related pages (including site management and data statistics).
Note: If the added site service is paused, users may encounter connection interruptions or fallback to direct origin access (Subject to DNS caching and resolution policies).
Service Recovery
Once you recharge and settle the arrears (i.e., Account Credit becomes positive), the system will automatically restore the site services stopped due to arrears.
You can immediately re-enter the CDN console for management operations.
