Interactions Between BFD and Graceful Restart
We have school holidays this week, so I’m reposting wonderful comments that would otherwise be lost somewhere in the page margins. Today: Dmitry Perets on the interactions between BFD and GR.
Well, assuming that the C-bit is set honestly (will be funny if not) and assuming that the Helper is using this bit correctly (and I think it’s pretty well defined what “correctly” means - see section 4.3 in RFC 5882), the answer is pretty clear.

The Three Stages of Monitoring on the Road to Observability
Getting to an advanced level of observability requires a monitoring evolution from reactive to proactive, and, finally, prescriptive monitoring.VMware Tanzu Service Mesh Named a Leader in GigaOm Radar Report on Service Mesh
GigaOm placed VMware Tanzu Service Mesh (TSM) in the leader ring of its 2021 GigaOm Radar Report for Evaluating Service Mesh, cementing VMware’s status as the open-source choice for connecting and securing modern applications across single and multi-cloud environments.
As enterprises continue to split applications into microservices that can be spun up or down as needed, service meshes give DevOps the ability to seamlessly and simply orchestrate connectivity and security services across multi-cloud environments, automatically and at scale. This common abstraction layer for application services enables true app resiliency, observability, and security across single and multi-cloud environments — a critical superpower for organizations focused on delivering powerful and consistent experiences.
VMware continues to lead
Citing Tanzu Service Mesh’s open-source architecture, dominance in the enterprise market, innovative road map, and focus on improving security, the authors of the report feel that Tanzu Service Mesh gives enterprises the best chance of gaining that all-important visibility and control with modern applications.
The key to this, of course, is Tanzu Service Mesh’s ability to seamlessly abstract the application layer from the infrastructure layer through Global Namespace (GNS). By onboarding applications to a Global Namespace, developers, operations, and security gain consistent policy controls and operational Continue reading

Sudan woke up without Internet
Today, October 25, following political turmoil, Sudan woke up without Internet access.
In our June blog, we talked about Sudan when the country decided to shut down the Internet to prevent cheating in exams.
Now, the disruption seems to be for other reasons. AP is reporting that "military forces ... detained at least five senior Sudanese government figures.". This afternoon (UTC) several media outlets confirmed that Sudan's military dissolved the transitional government in a coup that shut down mobile phone networks and Internet access.
Cloudflare Radar allows anyone to track Internet traffic patterns around the world. The dedicated page for Sudan clearly shows that this Monday, when the country was waking up, the Internet traffic went down and continued that trend through the afternoon (16:00 local time, 14:00 UTC).
We dug in a little more on the HTTP traffic data. It usually starts increasing after 06:00 local time (04:00 UTC). But this Monday morning, traffic was flat, and the trend continued in the afternoon (there were no signs of the Internet coming back at 18:00 local time).
When comparing today with the last seven days' pattern, we see that today's drop is abrupt and unusual.
We can see Continue reading

A big part of the job of a technical writer is getting feedback on the content you produce. Writing and maintaining product documentation is a deeply collaborative and cyclical effort — through constant conversation with product managers and engineers, technical writers ensure the content is clear and serves the user in the most effective way. Collaboration with other technical writers is also important to keep the documentation consistent with Cloudflare’s content strategy.
So whether we’re documenting a new feature or overhauling a big portion of existing documentation, sharing our writing with stakeholders before it’s published is quite literally half the work.
In my experience as a technical writer, the feedback I’ve received has been exponentially more impactful when stakeholders could see my changes in context. This is especially true for bigger and more strategic changes. Imagine I’m changing the structure of an entire section of a product’s documentation, or shuffling the order of pages in the navigation bar. It’s hard to guess the impact of those changes just by looking at the markdown files.
We writers check those changes in context by building a development server on our local machines. But sharing what we see locally with our stakeholders has Continue reading
Feedback: How Networks Really Work
A few weeks ago I asked my subscribers which webinar they’d like to see in November (thanks a million to everyone who replied!). Not surprisingly, network automation got the top spot, but I was a bit sad to see my long-term pet project at the bottom of the list:

Deploying High Performance Pure Virtual Linux Router – 6WIND
Hello my friend,
Network Function Virtualisation (NFV) is not a new topic. There are numerous blogpost and articles, even in our blog, which review this topic. Yet, there is much more we can cover. Today we’ll share some insights on one of the very interesting products existing on the market today: 6WIND vRouter Turbo Router. We have a limited amount of days to write a few articles under our evaluation license. Hence, we’ll focus only on the most critical elements.

Is Linux Suitable for Automation?
It absolutely is. In fact, Linux is the real home for automation systems, as in many cases it hosts the tools you create in Ansible, Python, Bash, Go or any other language. At the same time, in order to effectively work with Linux, you need to know how to automate management and operation of Linux operating system itself. And you will be absolutely capable to do that, once you attend our Continue reading
