Comcast Business (“Comcast”) strives to provide consumers with accessible, easy-to-understand information about the services we provide, so they can make informed decisions about which services best meet their needs. Consistent with that goal, we have established this page as a single place where consumers and others can access and review the relevant policies, agreements, and other information about Comcast Business broadband Internet access services (“Business Internet”).

Additionally, the Federal Communications Commission ("FCC") requires that Comcast and other providers of broadband Internet access services disclose certain information regarding those Internet services. The information required for disclosure under the FCC's rules is found below and in the various policies and documents listed and linked on this page. To assist you in finding the information you're looking for, we highlight below information that the FCC specifically calls for in the Open Internet Disclosures.

Network Practices

Comcast does not discriminate against lawful Internet content, applications, services, or non-harmful devices. The bullets below provide an overview of Comcast's network practices with respect to its Business Internet services. Additional information, including more-detailed technical information, is available in the Comcast Business Internet Network Management page.

Blocking

Comcast does not block or otherwise prevent end user access to lawful content, applications, services, or non-harmful devices. Comcast does engage in reasonable network management practices described below and in our Comcast Business Internet Network Management page.

Throttling

Comcast does not degrade or impair access to lawful Internet traffic on the basis of content, application, service, user, or use of a non-harmful device. Comcast does engage in reasonable network management practices described below and in our Comcast Business Internet Network Management page.

Affiliated Prioritization

Comcast does not directly or indirectly favor some traffic over other traffic, including through use of techniques such as traffic shaping, prioritization, or resource reservation, to benefit an affiliate.

Paid Prioritization

Comcast does not directly or indirectly favor some traffic over other traffic, including through use of techniques such as traffic shaping, prioritization, or resource reservation, in exchange for consideration, monetary or otherwise.

Network Management

Comcast manages its network with one goal: to deliver the best possible broadband Internet access service to all of its customers. To further this effort, Comcast uses reasonable network management practices that are consistent with industry standards. Comcast uses various tools and techniques to manage its network, deliver its service, and ensure compliance with the Acceptable Use Policy for Comcast Business Internet Services, Business Services Customer Terms and Conditions, and any other applicable terms, conditions, and agreements. These tools and techniques are dynamic and can and do change frequently. Network management activities may include identifying spam and preventing its delivery to customer email accounts, detecting malicious Internet traffic and preventing the distribution of, or inadvertent access to, malware, phishing, viruses, or other harmful code or content.

As the Internet and its related technologies continue to evolve, Comcast’s network management tools will also keep pace so we can deliver an excellent, reliable, and safe experience to all of our customers. We will provide updates here as well as other locations if we make significant changes to our network management techniques.

Comcast currently does not maintain a separate system to assist with managing times of congestion. As our network technologies and usage of the network continue to evolve, we reserve the right to implement a new congestion management system if necessary in the performance of reasonable network management and in order to maintain a good broadband Internet access service experience for our customers, and will provide updates here as well as other locations if a new system is implemented.

Application-Specific Behavior

Comcast provides its Business Internet customers with full access to all the lawful content, services, and applications that the Internet has to offer. Comcast does not block or rate-control specific protocols or protocol ports (except to prevent spam, malicious attacks, and identity theft), does not modify protocol fields in ways not prescribed by protocol standards, and does not otherwise inhibit or favor certain applications or classes of applications.

Device Attachment Rules

Many devices are approved to access our Business Internet service. In order for a cable modem device to be approved for use on the network, it must pass CableLabs certification, UL certification, FCC certification, and Comcast device testing covering areas like DOCSIS and WiFi performance, security, and integration with Comcast’s network and systems. Comcast contracts with a third-party, Kyrio, to perform certain device testing on Comcast's behalf. You can access a comprehensive list of all currently approved cable modems and EMTA devices here. For details about testing and certification requirements for DOCSIS-compliant devices for use on the Comcast network, contact Retail_Team@comcast.com. From time to time Comcast may “end of life” certain cable modem devices or cease permitting those devices to attach to the network for network management and security reasons.  Please see Use approved third-party equipment for Business Internet to learn more. 

Security

Comcast employs a number of practices to help prevent unwanted communications, such as spam, and protect the security of Comcast's customers and network. We limit the number of login, SMTP, DNS, and DHCP transactions per second (at levels far above “normal” rates) that customers can send to our servers in order to protect them from Denial of Service (DoS) attacks. (We do not disclose exact rate limits in order to maintain the effectiveness of these measures.) Please see Email - Limitations on Sending and What is Comcast Doing About Spam? to learn more.

In order to further protect our customers, Comcast blocks a limited number of ports that are commonly used to send spam, launch malicious attacks, or steal a customer’s information. Comcast conducts several security initiatives, and offers security tools for our customers at our online security page. For more information, see List of Blocked Ports.

Performance Characteristics

Service Description

Comcast provides a detailed summary of its Internet service performance containing information about speed and latency, as well as other related topics. Comcast has always prided itself on providing state-of-the-art broadband services at the highest possible speeds. It consistently delivers at or above the "provisioned" speed for the particular service tier. Comcast also provides a speed test page, so you can test your connection for yourself.

Other Services on Our Network

Comcast currently provides cable services (using both digital QAM and Internet Protocol (“IP”)-based technologies), and voice services and certain Metro-Ethernet enterprise business services (using IP-based technologies), to its customers over the same physical network used to deliver Business Internet service to small and medium sized business customers. Our IP cable and voice services, and our Metro-Ethernet enterprise business services, are not provided over the Internet but are provisioned with separate service capacity and delivered over separate service flows using Differentiated Service Code Point (“DSCP”) technology, and the voice and Metro-Ethernet (but not the video) services are marked for prioritization (to ensure that calls, e.g., 911 calls, go through even in times of congestion). These services are designed to protect the integrity and reliability of the Business Internet service, which is delivered on a best-efforts basis.
