Today we announced our new Constant GuardTM security program. We are also testing a feature of Constant GuardTM called a "Service Notice," designed to send customers a message when we believe their computer has been infected with a virus or other malware. For additional information, please visit our blog post on this subject.
Prior to the start of this trial, we developed the a draft document with the Internet Engineering Task Force (IETF) regarding remediation of malicious bots, available for review and comment by the Internet community at http://tools.ietf.org/html/draft-oreirdan-mody-bot-remediation. In addition, for the same purposes, we have developed a draft document with the IETF which describes in detail how the Service Notice system works, available at https://datatracker.ietf.org/doc/draft-livingood-web-notification/.

At Comcast, we are constantly looking to deliver a better high-speed Internet and online search experience. That is why we have begun market testing Domain Helper in selected areas to help customers find the Web sites they want when they mistype a Web address name in a Web browser's address bar. Those market areas are: Arizona, Colorado, New Mexico, Oregon, Texas, Utah, and Washington.
Some customers will not want the assistance of Domain Helper, so there is an easy way to opt-out of this when you receive the suggestion Web page (or by visiting the opt-out page now -- note also that customers with statically-configured Comcast DNS servers are opted-out by default). We have also developed the first draft of a new best practices document with the IETF regarding these types of services, available for Internet community review and comment at http://tools.ietf.org/html/draft-livingood-dns-redirect-00.
We hope our customers find this to be a valuable tool. For additional information, feel free to visit our blog post on this subject.

In March 2008, we announced that by the end of the year Comcast would switch to a new network management technique for managing congestion on Comcast's broadband network. Effective December 31, 2008, we have completed this transition, which is now part of our daily business operations for managing congestion on our network. The approach is designed to ensure, to the greatest extent possible, that all of our high-speed Internet customers have fair and equal access to the Internet and to bandwidth resources.
On these Web pages, we have provided information and FAQs about congestion management and we have posted copies of the documents we filed with the FCC that also describe it in great detail. Please read more about network management or read some FAQs.

As part of continuing efforts to increase our transparency on our network management methods, we have updated and expanded our FAQs. We have recently published a new FAQ regarding the network ports which are blocked for security reasons, in order to protect our customers. It is available at here in our FAQs.

IETF 73 will include P2P and network management-related topics, as a follow-up to the 72nd IETF meeting in July, 2008. The 73rd IETF meeting will take place in Minneapolis in November. We anticipate participating in a variety of working groups relevant to this topic, including Techniques for Advanced Networking Applications (TANA) and Application-Layer Traffic Optimization (ALTO) Birds of a Feather (BoF) meetings. In preparation for the ALTO BoF, where P4P-like mechanisms are being discussed, we have submitted in Internet Draft describing our recent P4P technical trial results, which is available here.

We are expanding our previously announced network management trial to the areas of Colorado Springs, CO, East Orange, FL, and Lake City, FL. We expect to continue these trials for at least 30 days as we evolve the new protocol-agnostic network management technique.
These trials which started in March 2008 are ongoing in the previously-announced markets of Warrenton, VA, and Chambersburg, PA

IETF 72 will include P2P and network management-related topics, as a follow-up to the IETF P2PI Workshop in May. The 72nd IETF meeting will take place next week in Dublin, Ireland. While some of this follow-up work will occur in regular IETF workgroup groups, most of it will take place in the Techniques for Advanced Networking Applications (TANA) and Application-Layer Traffic Optimization (ALTO) Birds of a Feather (BoF) meetings. Comcast is participating in IETF 72.
