Craig Labovitz reporting from Arbor Networks: "We use ATLAS data to graph Facebook (AS32934) traffic with 80 ISPs around the world between 5pm September 22 and 5pm EDT today. You can see Facebook traffic plummet around 1:30pm and return shortly after 4pm. From a quick glance at the data, the outage appears to be global (impacting most of the 80 ISPs)." more
The Italian Red Cross says residents' home networks can assist with communications during the search for survivors following Wednesday's 6.2 magnitude earthquake which struck central Italy killing over 240 people. more
Recently, BII-Global SDN Certified Testing Center (SDNCTC EN | CH) issued the Performance Test White Paper for SDN Controller (hereinafter Whitepaper) at China Future Network and Development Innovation Forum, which truly fills the vacuum in SDN controller performance testing at home. It, by means of elaborate results from the open-source controller tests, provides reliable analysis report to all corners within the industry, which has been highly thought of and widely supported by experts both at home and broad. more
Internet monitoring companies say Syria's Internet connectivity has been shutdown nationwide. Renesys, a U.S.-based network security firm that studies Internet disruptions, reports that about 6 hours ago (12:26pm in Damascus) Syria's international Internet connectivity was shut down. "In the global routing table, all 84 of Syria's IP address blocks have become unreachable, effectively removing the country from the Internet." Akamai Technologies Inc. has also confirmed the complete outage in Syria. more
Unless you have a team employing the latest proactive threat-hunting techniques, the stealthy Advanced Persistent Threat (APT) hiding in your network can pass by completely unnoticed. There are as many definitions of APT as experts writing about the topic, so let's boil it down to the simple essentials: APTs are usually implanted and maintained by a team of malicious actors with the intention of living long term in your network while extracting valuable private information. more
2022 was not a normal year for me. We sold our company of almost 25 years to Interlan Gefle AB to Nordlo Group, and I also moved away from Gävle city to Boänge, a small rural village outside Sandviken where my ISP (AS20626) still isn't ready for IPv6 in my location.... ☹ ( I use a Mikrotik with a Wireguard tunnel to solve my IPv6 today.) It's 2023 when I'm writing this, and I can't understand why ISPs still haven't deployed IPv6! more
Network security experts from across the U.S. government told a U.S. Senate Armed Services Subcommittee on Tuesday that federal networks have been thoroughly penetrated by foreign spies, and that current perimeter-based defenses that attempt to curb intrusions are outdated and futile. more
I saw a poster on the London Underground yesterday, and as is often the case it got me thinking about the parallels with telecoms. The poster explains the peak and off-peak fare structure for tube travel. The purpose of this pricing system is to manage the relationship between supply and demand in a system that is capacity constrained. Over short and medium timescales the supply is essentially fixed, and demand can oversaturate that supply. more
At NANOG on the Road (NotR) in September of 2018, I participated in a panel on BGP security -- specifically the deployment of Route Origin Authentication (ROA), with some hints and overtones of path validation by carrying signatures in BGP updates (BGPsec). This is an area I have been working in for... 20 years? ... at this point, so I have seen the argument develop across these years many times, and in many ways. more
Ubiquiti Networks Inc., a San Jose based maker of networking technology, has disclosed that cyber criminals stole $46.7 million via a "business email compromise fraud involving employee impersonation." more
Cable operators face a big challenge today as data utilization continues to increase on their networks. Keeping up with the demand for high quality services while upgrading network infrastructure seems to be a never-ending task. Many times, network upgrades are done without much help from tools and systems, leaving it mostly based on experience and performance indicators defined by the operator. Unfortunately, this is the reality for far too many service providers today. more
Do you know someone who has made outstanding contributions in service to the Internet community? Someone who has made the Internet better in some way who deserves more recognition? Maybe someone who has helped extend Internet access to a large region? Or wrote widely-used programs that make the Internet more secure? Or served in some capacity behind the scenes in Internet services? more
"Many refugees regard a connected device as being as vital to them as food, water or shelter," according to a new report from the UN Refugee Agency (UNHCR), and Accenture. more
A few years ago, there were a lot of predictions that we'd see broadband networks converting to quantum technology because of the enhanced security. As happens with many new technologies, quantum computing is advancing at a slower pace than the wild predictions that accompanied the launch of the new technology. more
Would you like to help guide the future of the Mutually Agreed Norms for Routing Security (MANRS) initiative? As the MANRS community continues to develop new efforts to make the routing layer of the Internet more secure (ex. the equipment vendor program), would you like to help lead the work? The MANRS community is seeking volunteers for its new Steering Committee. The committee will lead the community as it evolves its governance model. more
