PUSHR CDN utilises two different billing models to provide a cost-effective and flexible solution that caters to customers with both regular and irregular traffic patterns. 95th percentile burstable billing is applied to unmetered bandwidth plans while per-TB billing is used for metered traffic plans. Allocated bandwidth or traffic are sold in 100Mbps and 1TB increments respectively.

Account top ups

All services provided by PUSHR CDN require customers to keep a positive balance in their account's profile. When you add credit to your account via the top up option, this credit is used to fund the services and resources used by you. Where VAT is applicable, the VAT amount will be deducted from the payment amount and the remaining credit will be applied to your account.

Individuals and companies based outside of the EU, as well as companies operating from within the EU with a valid VAT number are exempt from VAT tax.

The 95th percentile bandwidth billing

PUSHR's 95th percentile bandwidth measurement has been designed to protect you from unexpected bandwidth spikes, allowing you to peak beyond your plan's included bandwidth for a total of 5% of the time per month (a total of 72 minutes per day) at no additional cost. This amount of extra bandwidth is called burst bandwidth. There is no upper limit on the amount of bandwidth that could be used during bursts, and as long as the combined burst time during any day is equal to or less than 72 minutes in total no additional charges will be billed. Due to it's nature, burst bandwidth is not guaranteed and while PUSHR CDN conforms to the industry's best practises for timely capacity provisioning, we can only guarantee and dedicate bandwidth as part of your monthly commitment.

* 95th percentile overage fees

If the burst time of your CDN zone passes the 72 minutes mark in any given day and the burst bandwidth is less than 100% of your allocation, PUSHR will send an automatic email notification the first time to inform you of your high usage. If the mark is passed for a second time during the current billing period, the overage will be applied and will be added to your next bill. Where the burst passes the 180 minutes mark in any given day or the burst passes the 72 minutes mark and equals to or is larger than 100% of your allocated bandwidth, the overage will be billed automatically.


Included Mbps Usage(Mbps) Burst(Mbps) Burst(%) Burst (t) Occurrences Charges
500 750 250 50% <72 min None. Burst is within time limits.
500 1100 600 120% <72 min None. Burst is within time limits.
500 750 250 50% >72 min 1st No overage. Email notification sent.
500 750 250 50% >72 min 2nd 250Mbps overage applied to next bill.
500 1100 600 120% >72 min 1st 600Mbps overage billed automatically.
500 750 250 50% >180 min 1st 250Mbps overage billed automatically.

As seen in the table above, the amount of burst bandwidth and the total burst time during a given day would determine if an overage fee is to be incurred. Once the overage is applied, the burst bandwidth becomes part of your allocation for the current billing period and you can safely use it for the remainder of the month.

The following visualisation of a PUSHR CDN customer's bandwidth usage clearly demonstrates the benefits of the 95th percentile billing for websites and apps with regular & heavy traffic patterns. In this example, our customer has burst at 586.91Mbps during one day in their current billing period, and has used up to 560Mbps on few other days, but their 95th percentile usage is calculated at 338.62Mbps, which is well within their 400Mbps bandwidth plan. Since their traffic is predictable and it's pattern is repeating, the 95th percentile model saved them $1200 last year alone.

Bandwidth usage should be monitored. You can opt-in to receive automatic alerts via SMS when your CDN zone's bandwidth usage reaches a predefined threshold to avoid unexpected overages. SMS Alerts are free for zones with 1Gbps+ allocations, and $0.5 per message for lower plans.

Metered plans

Metered plans are offered at a fixed price per month, measured in TB (terabytes). As with bandwidth, only outbound traffic is measured while inbound traffic is free of charge. Each metered plan includes a set amount of traffic that you can use per month (except for the Pay-As-You-Go plan where traffic can be used over any period of time). For every TB (terabyte) beyond your plan's included traffic an overage is applied. Pricing, volume discounts and overage fees are available here.

* Metered plans overage fees

Overages (for plans below 11TB) or extra traffic (on the 11TB plan) are recalculated hourly and reported both on the top bar of your dashboard and on the billing page, where a cost breakdown of all billed services is being presented. If your account has generated less than $100 in overages, the overage fees will be added to your next bill and therefore will not be visible in the costs breakdown until the start of your next billing cycle. If the overages amount to $100 or more, we will automatically bill your account credit to cover the extra usage.

If your account credit is insufficient, we will email you and will allow 72 hours to add funds. If your overage usage reaches $150 and you have still not added funds in your account, your service will be temporarily suspended.

* Notifications regarding traffic usage
  • For plans up to 10TB, we will send you an email notification once you have reached 75% of your traffic quota, and then once again when you reach 100%.

  • Customers on our 11TB plan receive a single notification once they have used the whole 11TB.

Plan upgrades

PUSHR's customers can upgrade their plan at any point in time during their billing period to avoid overage fees. During an upgrade the customer is required to pay only the difference between their current plan and the new plan, where this difference is calculated proportionally to the time left on the the old plan of the customer by PUSHR at the time of the upgrade. The day of the upgrade becomes the new billing date for the upgraded CDN zone.

Add-ons pricing

All service add-ons are billed on a monthly basis. When an add-on service is being added or upgraded at a date other than the billing date of the CDN zone, the cost is calculated proportionally to the remaining days in the current billing period.


An invoice is generated for every account top up transaction. It is then immediately available for review or download from your dashboard's billing panel. Where VAT tax is applicable, the VAT amount is calculated and deduced from the total amount of the top up transaction. The remaining credit after VAT deduction is then applied to your account. Past invoices are available for review and download in your account's billing panel.

Service costs breakdown

The exact cost of each service in your account, including bandwidth/traffic and storage for the current billing period is always available in the Billing section of your account's dashboard.
