In October 2009, we announced the market trial of our new Constant Guard™ bot detection and notification system. The system was designed to detect bot activity and send customers a "Service Notice" when we believe their computer has been infected with a bot or other malware. Based on the success of the market trial, we have decided to rollout the bot detection and notification system to our entire network over the next few months. For additional information, feel free to visit our blog post or our Constant Guard™ page.

Today in Brussels, the Public Interest Registry, operator of the .ORG Top Level Domain (TLD), announced that they have signed the .ORG TLD, enabling support for DNSSEC in that TLD. Coinciding with that announcement and joint testing we have performed with PIR, Comcast is pleased to sign all of our over 650 .ORG domains. This is an important milestone in our continuing work to deploy DNSSEC. You can learn more about this on the Comcast DNSSEC Information Center website at http://www.dnssec.comcast.net and you can find slides we will be presenting at two ICANN DNSSEC workshops tomorrow here and here.

Comcast has been a leader in testing of and advocating for the wide adoption of DNSSEC. Our leadership continues today with the announcement of a plan to implement DNSSEC validation in the DNS servers that our customers use by the end of 2011, as well as for signing of our authoritative domains, such as comcast.com, by the end of the first quarter of 2011. In addition, today we are making available DNSSEC-validating DNS servers for customers to use on a trial basis now. You can learn more about this on the Comcast DNSSEC Information Center website at http://www.dnssec.comcast.net.

Comcast has been a leader in IPv6 development for many years. Our leadership continues today with the announcement of a plan to conduct real, production-network trials of IPv6 technology this year. The transition from IPv4 addresses to IPv6 addresses is a necessity, as the available pool of IPv4 addresses will at some point be exhausted for all Internet users.
These trials will help Comcast to identify and solve any areas of difficulty involved in the transition to IPv6, and to determine what approach will be the easiest and most seamless to our customers. Comcast will continue to share what we learn with the Internet community, particularly with the IETF, for the benefit of other users of the Internet.
Customers who are interested in volunteering to participate in these IPv6 trials, can express their interest using the online form on the Comcast IPv6 Information Center website, at http://www.comcast6.net.

Today we announced the start of a pilot market deployment of our data usage meter for our High-Speed Internet Service. This deployment begins today for customers in Portland, Oregon. We currently anticipate deploying this usage meter beyond the pilot market beginning in the first quarter of 2010. You can find FAQs here, and an independent analysis of the usage meter by NetForecast, Inc. here. The usage meter looks like this. Feel free to visit our customer support forums if you'd like to ask us more questions.

The MIT Internet Traffic Analysis Study (MITAS) is a new research project at the MIT Computer Science and Artificial Intelligence laboratory (CSAIL). The goal of this project is to undertake novel empirical research of ISP traffic data. Data will be collected from at least six participating ISPs, including Comcast, and the project hopes to add more ISPs. Better data and collection methodologies are needed to inform the industry, the network research community, and policy discussions about appropriate technical and business approaches to traffic management.
Detailed traffic data will be collected from ISPs over time, enabling researchers to formulate empirically valid characterizations of both aggregate traffic patterns, as well as a traffic profile for the average users. It is important to note that no personally identifiable information about any participating ISPs' users will be used in this project.
More information about the MITAS research project can be found at the MITAS website, at http://mitas.csail.mit.edu.

In July 2009, we announced our market trial of our new Domain Helper service, designed to help customers find Web sites they want when they mistype an address in the web browser's address bar. Based on the success of the market trial, we have decided to roll out the service to our entire network. Customers will receive an email explaining the service and how to opt-out shortly, but can certainly opt-out now as well. Please note that customers with statically-configured Comcast DNS servers are opted-out by default.
