Many media sources have reported outages in Iranian mobile networks and Internet services in the wake of Friday's controversial elections. We took a look at the state of Iranian Internet transit, as seen in the aggregated global routing tables, and found that the story is not as clear-cut as has been reported. There's no question that something large happened in the Iranian telecom space, and that the timing aligns with the close of voting and the emerging controversy... more
In a U.S. congress hearing held yesterday November 9th, significant focus was projected on "network neutrality" and a new telecommunications bill affecting the Internet. "This bill could fundamentally alter the fabulously successful end-to-end Internet," says Alan Davidson in the post on Google blog. Vint Cerf was not able to testify because of the Presidential Medal of Freedom award ceremony at the White House, but submitted the following letter to the hearing... more
The Starlink Web site says, "Starlink is targeting service in the Northern U.S. and Canada in 2020, rapidly expanding to near-global coverage of the populated world by 2021," but the rollout will not be uniform. The initial coverage will be centered around 53 degrees latitude, and locations with unobstructed views of the sky will have an advantage. Like many folks, I wonder about coverage at my particular location in a wooded mountain area at 34.8462° N latitude. more
SpaceX began public beta testing of the Starlink Internet service in the northern US late last October. Since then, they have made many software updates based on the beta experience and have expanded the uninterrupted-coverage area by launching new satellites. By the end of the year, they had begun beta service in southern Canada and sent beta test invitations to a few UK users. The beta-eligibility area is expected to expand from the current 45-53 degree latitude this month or next. more
The Wall Street Journal reported that AT&T saw wireless networks about to drown under a deluge of data. To see YouTube content uploaded form an iPhone or Slingbox rerouting a favourite television program to your smart phone gives mobile network operators the shivers. Skype over 3G in the meantime gives sleepless nights, not because of surging megabyte floods but due to nightmares of considerable voice and roaming revenues washing away. Not easy to plan and engineer "managed transitions" under those circumstances. more
It is once again time for our annual review of posts that received the most attention on CircleID during the past year.

"Major Mobile US Networks Pass 50% IPv6 Threshold," reports Mat Ford, Technology Program Manager at the Internet Society (ISOC). more
Cuba's primary connection to the global Internet is through the ALBA-1 undersea cable linking landing points on the south-east shore of the island to Venezuela and Jamaica; however, the bulk of Cuban traffic originates in Havana which is on the north-west coast. Traffic from Havana and other cities in the west travels over a backbone to reach the cable landing points. A landing point near Havana would reduce the load on the backbone... more
Note: this is an update on my earlier story, which incorrectly said that the AP reported that Chairman Martin was seeking to impose "fines" on Comcast. In fact, the story used the word "punish" rather than "fine," and a headline writer at the New York Times added "penalty" to it "F.C.C. Chairman Favors Penalty on Comcast" (I won't quote the story because I'm a blogger and the AP is the AP, so click through.) Much of the initial reaction to the story was obviously colored by the headline. more
Until the pandemic hit, I rarely thought about upload bandwidth. I mostly used upload bandwidth to send files to people, and I rarely cared if they received the files immediately -- I was happy as long as files got sent. But the pandemic changed everything for millions of people. All of a sudden, homes were unable to function well due to problems with uploading. more
Today the FCC announced the winners of the 700 MHz auction -- and you can see from pp. 62-63 of this document that Verizon won Block C. (Block C was set up in two nationwide paired blocks of 11 MHz each, which were auctioned off in very large geographic areas -- 12 licenses, each covering a "Regional Economic Area Grouping". Verizon won seven of the twelve licenses, covering all of the US except Alaska, Puerto Rico, American Samoa, Guam, and the Northern Mariana Islands.) Why does this matter? more
It might seem a little strange, but in the current economics of the market in registration of DNS names it appears that the set of names that are not "visible," or at least not associated with any dedicated network service point, represents a far larger set, and has a far higher total value to the DNS name registration industry, than the set of network-visible service endpoint domain names. In other words, there appears to be a larger and more valuable market for names that do not exist than for names that do. more
As founder and CTO of Ellacoya Networks, a pioneer in Deep Packet Inspection (DPI), and now having spent the last year at Arbor Networks, a pioneer in network-based security, I have witnessed first hand the evolution of DPI. It has evolved from a niche traffic management technology to an integrated service delivery platform. Once relegated to the dark corners of the central office, DPI has become the network element that enables subscriber opt-in for new services, transparency of traffic usage and quotas, fairness during peak busy hours and protection from denial of service attacks, all the while protecting and maintaining the privacy of broadband users. Yet, DPI still gets a bad rap... more
I recently had the opportunity to interview, Richard Whitt, Google's Washington Telecom and Media Counsel, who will be one of the keynote speakers at the upcoming Emerging Communications Conference (eComm 2009) being held on March 3-5 at the San Francisco Airport Marriott. The following is the transcript of our phone conversation and the audio recording of the interview. more
SpaceX on Tuesday disclosed that it has received 500,000 preorders for its Starlink satellite internet service and that it anticipates no technical problems meeting the demand. more
