Comcast provides residential and commercial customers with a variety of high speed Internet plans from which to choose, ranging from our Economy tier (with download speeds up to 1.5 megabits per second ("Mbps"), and upload speeds up to 384 kilobits per second ("kbps")) to our Extreme 105 tier (with download speeds up to 105 Mbps, and upload speeds to 10 Mbps). Comcast provisions its customers’ modems and engineers its network to ensure that its customers can enjoy the speeds to which they subscribe. However, Comcast does not guarantee that a customer will actually achieve those speeds at all times. Without purchasing an expensive, dedicated Internet connection, no Internet service provider ("ISP") can guarantee a particular speed at all times to a customer. Comcast advertises its speeds as "up to" a specific level based on the tier of service to which a customer subscribes. Read much more about this topic here.

As noted on our blog, starting today we will begin migrating customers who have opted out of our Domain Helper service over to our production DNSSEC-validating servers. This will happen first in a selected part of our Virginia network, and will later expand to all markets in the following sixty days, at which point all of our customers who have opted out of Domain Helper will be migrated. After this has been completed, we will migrate the rest of our customers, which we anticipate will stretch into the early part of 2011. To understand what will happen when a DNSSEC validation failure occurs, see this validation failure FAQ. You may also want to check out this brief introductory video about DNSSEC, as well as our Constant Guard™ page. We've also updated all of our DNSSEC FAQs here.

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.
