DNS Oblivion

The problem with both DoH and DoT is that neither is all that satisfactory from a privacy standpoint. It is more of a compromise approach that poses a difficult question to me, as the end user. If I have to compromise my privacy to a third party and expose the combination of my identity and the DNS queries I make, then who should be privy to this information? Which third party DNS provider represents the least risk to me now and in the future? It's a tough question, and the best answer not having to compromise my privacy at all.

Pulling Back the Curtains

One of the major sources of complexity in modern systems is the simple failure to pull back the curtains. From a recent blog post over at the ACM—

The Wizard of Oz was a charlatan. You’d be surprised, too, how many programmers don’t understand what’s going on behind the curtain either. Some years ago, I was talking with the CTO of a company, and he asked me to explain what happens when you type a URL into your browser and hit enter. Do you actually know what happens? Think about it for a moment.

Yegor describes three different reactions when a coder faces something unexpected when solving a problem.

Throw in the towel. Just give up on solving the problem. This is fairly uncommon in the networking and programming fields, so I don’t have much to say here.

Muddle through. Just figure out how to make it work by whatever means necessary.

Open the curtains and build an excellent solution. Learn how the underlying systems work, understand how to interact with them, and create a solution that best takes advantage of them.

The first and third options are rare indeed; it is the second solution that seems to dominate our Continue reading

The Week in Internet News: Facebook Faces U.S. Antitrust Lawsuits

"In the news" text on yellow background

Do not pass go: The U.S. Federal Trade Commission and attorneys general from 46 states have filed antitrust lawsuits, charging the social media giant Facebook of expanding its monopoly position by acquiring potential rivals including WhatsApp and Instagram, The Hill reports. It’s possible that Facebook would be required to sell off those acquisitions. Facebook has noted that both acquisitions were approved by regulators at the time.

Get off my phone: The government of China has ordered several apps, including one from TripAdvisor, to overhaul their products in an alleged crackdown on pornography and other “improper” content, The Associated Press says. In the meantime, China’s National Cyberspace Administration ordered the removal of 105 apps including TripAdvisor from app stores. The agency said there were public complaints about obscene, pornographic, and violent information as well as fraud, gambling, and prostitution.

Cookie spies: The government of France’s data privacy agency has fined Google US$121 million and Amazon $42 million for breaking the country’s rules on tracking cookies, Reuters says. The Google fine was the largest ever from the French Commission Nationale de l’Informatique et des Libertés. The CNIL said the companies’ French websites didn’t seek the prior consent of visitors before advertising Continue reading

Wide-open spaces: Big spectrum gains to boost Wi-Fi capability in 2021

Two recent FCC decisions will dramatically increase the capabilities of new Wi-Fi systems in the coming year, providing badly needed breathing room to the unlicensed wireless world.The first allocation, announced in April, will throw open the entirety of the 6GHz spectrum range for unlicensed use, and the second, rolled out late last month, adds a small but critical amount of spectrum to the 5GHz band.Both of these decisions are important to future Wi-Fi deployments because they directly affect the amount of spectrum available for Wi-Fi to operate in. More bandwidth means larger channels, which translates directly into improved throughput for users.To read this article in full, please click here

Improving Cloudflare’s products and services, one feature request at a time

Improving Cloudflare’s products and services, one feature request at a time
Improving Cloudflare’s products and services, one feature request at a time

I started at Cloudflare in April 2018. I was excited to join an innovative company that operates with integrity and takes customer needs into account when planning product roadmaps. After 2.5 years at Cloudflare, this excitement has only grown, as it has become even clearer that our customers’ feedback is essential to our business. At an all-hands meeting this November, Michelle Zatlyn, our co-founder and COO, said that “every time we see things and approach problems from the lens of a customer, we make better decisions.” One of the ways we make these decisions is through Customer Success Managers funneling our customers’ feedback to our product and engineering teams.

As a Strategic Customer Success Manager, I meet regularly with my customers to better understand their experience with Cloudflare and work cross-functionally with our internal teams to continually improve it. One thing my customers often mention to me, regardless of industry or size, is their appreciation that their feedback is not only heard but understood and actioned. We are an engineering-driven company that remains agile enough to Continue reading

HP Enterprise expands GreenLake program to cover HPC systems

When it bought Cray back in May 2019, HP Enterprise hinted at offering HPC systems as a service. Now it is delivering on that with the introduction of HPE GreenLake cloud services for HPC.HPE has made a lot of headway with its GreenLake program, the pay-per-use model created in response to the popularity of cloud service providers. It lets customers pay as if they are buying a cloud service, but it’s provisioned using infrastructure deployed at customer sites or in colocation facilities. Up to now it’s been used in standard IT applications, like app and Web serving or databases.To read this article in full, please click here

Business without labour, Automation without workers

First posted in Human Infrastructure Magazine in March 2020 Its fashionable in Enterprise IT is to reduce headcount. This reflects a wider business fashion of ‘business without labour’ that chases the dream of ‘profits without cost’. You see, investors watch ‘revenue per employee’ or ‘profit per employee’ and IT managers feel  pressure to ditch people […]

Partnering with Global Cyber Alliance on Open Standards, Routing Security, and More

Our work is strengthened, and our impact magnified, when we collaborate with partners to build a secure and trustworthy Internet for all. That’s why we’re proud to announce we’ve entered into a Memorandum of Understanding (MoU) with the Global Cyber Alliance (GCA) to work together on routing security, open Internet standards, and other areas of joint interest. The Global Cyber Alliance is an international, cross-sector effort dedicated to reducing cyber risk and improving our connected world.

This relationship is not new. The Internet Society and GCA have a long history of working together, from promoting email and Internet of Things (IoT) security to improving routing security, increasing deployment of open standards, and helping stakeholders participate meaningfully in the multistakeholder management of core Internet resources.

Both organizations have emphasized the importance of research, capacity building, and advocacy to develop key technologies and policies. This work helps promote the Internet, its resources, the need for vigilant user-enabled security, and the need for the Internet to remain open, inclusive, and an enabler of opportunities.

“We’re proud to extend and formalize our long-standing relationship with GCA to create real change for network operators and Internet users around the globe. By joining forces, we can promote enhanced Continue reading

Repost: Drawbacks and Pitfalls of Cut-Through Switching

Minh Ha left a great comment describing additional pitfalls of cut-through switching on my Chasing CRC Errors blog post. Here it is (lightly edited).

Ivan, I don’t know about you, but I think cut-through and deep buffer are nothing but scams, and it’s subtle problems like this [fabric-wide crc errors] that open one’s eyes to the difference between reality and academy. Cut-through switching might improve nominal device latency a little bit compared to store-and-forward (SAF), but when one puts it into the bigger end-to-end context, it’s mostly useless.
