Private 5G might just make you rethink your wireless options

The hype surrounding 5G ranges from Jetsons-like futurism to deep-in-the-rabbit-hole conspiracy theories. On the consumer side, 5G is still serving up more sizzle than steak, mainly because the technology is so new, handsets so few, and infrastructure still mostly 4G LTE or earlier, so developers are still figuring out how to take advantage of its capabilities.To read this article in full, please click here

Effects of the conflict in Sudan on Internet patterns

Effects of the conflict in Sudan on Internet patterns
Effects of the conflict in Sudan on Internet patterns

On Saturday, April 15, 2023, an armed conflict between rival factions of the military government of Sudan began. Cloudflare observed a disruption in Internet traffic on that Saturday, starting at 08:00 UTC, which deepened on Sunday. Since then, the conflict has continued, and different ISPs have been affected, in some cases with a 90% drop in traffic. On May 2, Internet traffic is still ~30% lower than pre-conflict levels. This blog post will show what we’ve been seeing in terms of Internet disruption there.

On the day that clashes broke out, our data shows that traffic in the country dropped as much as 60% on Saturday, after 08:00 UTC, with a partial recovery on Sunday around 14:00, but it has consistently been lower than before. Although we saw outages and disruptions on major local Internet providers, the general drop in traffic could also be related to different human usage patterns because of the conflict, with people trying to leave the country. In Ukraine, we saw a clear drop in traffic, not always related to ISP outages, after the war started, when people were leaving the country.

Here’s the hourly perspective of Sudan’s Internet traffic over the past weeks as seen Continue reading

How to shop for network observability tools

Today’s enterprise networks span on-premises and cloud environments, and it has become a lot harder for IT teams to maintain performance, reliability and security when some parts of the network are unknown or off-limits to traditional performance monitoring tools.“If you cannot get visibility into all the components comprising the digital experience, everything that is between the end user clicking the mouse to the deepest part of a cloud or data center network, then you are flying blind, you are incurring a lot of risk, and you could be overspending, too,” says Mark Leary, research director for network analytics and automation at research firm IDC.To read this article in full, please click here

Exploring bash builtins on Linux

You probably use some bash builtins fairly often whether or not you think of them as builtins or simply as commands. After all, bash builtins are commands, but not implemented as separate executables. Instead, they are part of the bash executable. In other words, they are "built into" bash, thus the term "bash builtins".If you're looking for a particular builtin, the which command isn't going to find it for you because it only looks through a collection of executables. This includes system commands like /bin/echo as well as scripts for which you have execute permission. Here's an example of which not finding anything:To read this article in full, please click here

Celebrating Australia’s Privacy Awareness Week 2023

Celebrating Australia’s Privacy Awareness Week 2023

When a country throws a privacy party, Cloudflare is there! We are proud to be an official sponsor of the Australian Privacy Awareness Week 2023, and we think this year’s theme of “Privacy 101: Back to Basics” is more important now than ever. In recent months, Australians have been hit with the news of massive personal data privacy breaches where millions of Australian citizens' private and sensitive data was compromised, seemingly easily. Meanwhile, the Australian Attorney General released its Privacy Act Review Report 2022 earlier this year, calling for a number of changes to Australia’s privacy regulations.

You’re probably familiar with the old-school privacy basics of giving users notice and consent. But we think it’s time for some new “privacy basics”. Thanks to rapid developments in new technologies and new security threat vectors, notice and consent can only go so far to protect the privacy of your personal data. New challenges call for new solutions: security solutions and privacy enhancing technologies to keep personal data protected. Cloudflare is excited to play a role in building and using these technologies to help our customers keep their sensitive information private and enable individual consumers to protect themselves. Investing in and offering these Continue reading

Interesting: BGP Zombie Outbreak on Juniper Routers

BGP zombies are routes in the BGP table that refuse to disappear even though they should have been long gone. Recent measurements estimate between 0.5% and 1.5% of all routes in the global BGP table are zombies, which sounds crazy – after all, BGP is supposed to be pretty reliable.

Daryll Swer identified one potential source – Juniper routers do not revoke suppressed aggregated prefixes – and documented it in Navigating a BGP zombie outbreak on Juniper routers.
