Fibercast provisions its customers' modems and engineers its network to enable customers to enjoy the speeds to which they subscribe. However, Fibercast does not guarantee that a customer will achieve those speeds at all times. Unless a customer purchases a dedicated Internet connection, no Internet Service Provider ("ISP") can guarantee a particular speed at all times. Fibercast advertises its speeds as "up to" a specific level based on the tier of service to which a customer subscribes. The "actual" speed that a customer will experience while using the service depends upon a variety of conditions, many of which are beyond the control of an ISP. These conditions include:
- Performance of a customer's computer, including its age, processing capability, operating system, the number of applications running simultaneously, and the presence of any adware and viruses.
- Type of connection between a customer's computer and modem. For example, in-home wireless connections between the computer and the router or modem may be slower than wired connections. In-home wireless connections also may be subject to greater performance fluctuations, caused by factors like interference and congestion. Fibercast recommends that customers confirm that their in-home wireless connections are able to support the speeds that Fibercast's services deliver. Certain older in-home wireless connections and routers cannot perform at the speeds delivered by Fibercast's higher speed tiers. Customers can purchase their modem and router, or they can lease the necessary equipment from Fibercast, though even wireless routers leased from Fibercast are subject to some of the same limitations mentioned above.
- The distance packets travel (round trip time of packets) between a customer's computer and their final destination on the Internet, including the number and quality of the networks of various operators in the transmission path. The Internet is a "network of networks." A customer's Internet traffic may traverse the networks of multiple providers before reaching its destination, and the capabilities of those networks may affect the overall speed of that Internet connection.
- Congestion or high usage levels at the website or destination. When you access a site or particular destination that is being visited by others at the same time, you may experience a slower connection if the site or destination does not have sufficient capacity to serve all of the visitors efficiently at the same time.
- Gating of speeds or access by the website or destination. To control traffic or performance, many websites limit the speeds at which a visitor can download from their site. Those limitations will carry through to a customer's connection.
- The performance of the cable modem you have installed. Modem performance may degrade over time, and certain modems are not capable of handling higher speeds.
There are speed tests that measure Internet performance. We have provided links to a few of these sites below for your reference. Please note, however, that all speed tests have limitations and flaws. Each of these tests measures limited aspects of an ISP's speed and therefore must be seen as a guide rather than definitive measurements of performance.
