OpenAccess Bandwidth Overview
OpenAccess makes every effort to maintain premium bandwidth connectivity to the rest of the world.

For customers with colocation, direct fiber-optic connectivity and for certain types of webhosting and VPS products, bandwidth is metered.  Typically a certain amount of bandwidth is included in your contract, and if you exceed that an overage fee applies.  Pricing for bandwidth on contract is substantially cheaper than for the same amount of bandwidth if it is billed as overage.
Understanding 95th percentile usage billing

What is the 95th percentile?

The 95th percentile is a mathematical calculation widely used to evaluate the regular, sustained utilization of your Internet connection.

This calculation says that 95% of the time, your usage is at or below this amount. With the top 5% of the bandwidth usage being considered as short spikes of atypical usage and discarded.  It is important to realize that the 95th percentile is not an average.

How does OpenAccess calculate the 95th percentile?

Our system collects samples from its routers and switches every 5 minutes. Since the samples are taken every 5 minutes, the data sample represents a 5 minute averaged bits per second value.

At the end of a term (such as a customer's billing cycle, typically monthly), these 5 minute bit per second values are gathered and sorted. The top 5% of the values, representing the highest points of bandwidth usage during the month, are discarded. The remaining highest sample of data is considered the 95th percentile sample and is used by our billing system.

95th percentile is calculated from the higher of your inbound or outbound traffic, not the sum of both.

How does OpenAccess bill based on the 95th percentile?

Once the 95th percentile value is generated, it is compared to the amount allowed in your contract. If you have used more bandwidth than allowed, you are charged overage based on the difference between the two numbers.

For the amount of bandwidth you have prepaid and for overage rates, please consult your contract or contact your OpenAccess account representative.

What services does OpenAccess use 95th percentile billing for?

We use 95th percentile billing for all data center services as well as Tier-1 fiber and Tier-1 microwave services where the customer circuit is configured at a full symmetric rate of 10mbps or higher.
