I’m a bit late posting this … but this Thursday (an odd day for me) I’m running How the Internet Really Works, Part 1, over at Safari Books Online. From the page:

Internet shutdowns harm societies, economies, and the global Internet infrastructure – that’s why we’re tracking disruptions on the Internet Society Pulse platform. There are thousands of disruptions to Internet access every day all over the world, but not all of them are the result of deliberate shutdowns. Lengthy outages are usually the result of technical errors, routing misconfigurations, or infrastructure failures. […]

Just about everyone prepends AS’ to shift inbound traffic from one provider to another—but does this really work? First, a short review on prepending, and then a look at some recent research in this area.
What is prepending meant to do?
Looking at this network diagram, the idea is for AS6500 (each router is in its own AS) to steer traffic through AS65001, rather than AS65002, for 100::/64. The most common method to trying to accomplish this is AS65000 can prepend its own AS number on the AS Path Multiple times. Increasing the length of the AS Path will, in theory, cause a route to be less preferred.
In this case, suppose AS65000 prepends its own AS number on the AS Path once before advertising the route towards AS65001, and not towards AS65002. Assuming there is no link between AS65001 and AS65002, what would we expect to happen? What we would expect is AS65001 will receive one route towards 100::/64 with an AS Path of 2 and use this route. AS65002 will, likewise, receive one route towards 100::/64 with an AS Path of 1 and use this route.
AS65003, however, will receive two routes towards 100::/64, one with an AS Continue reading

From the community: A new poll from Morning Consult finds that more than half of U.S. residents trust local governments to provide broadband services, and just 14 percent believe local governments should be prohibited from providing broadband. Currently, 18 states limit or outright prohibit local governments from providing their own broadband. In those states, “these […]

Red Hat Ansible Network Automation continues to be a popular domain for Red Hat Ansible Automation Platform. We have continually developed additional resource modules to make automating network appliances easier, and more approachable, for novices and experts alike. These resource modules provide a consistent experience across multiple network vendors. There are seven main state parameters for resource modules: merged, replaced, overridden, deleted, gathered, rendered and parsed. The Ansible network team is adding one more parameter, purged, to this tool chest for resource modules. This blog will cover the purged parameter and show use-cases through a practical example.
For this example, we will be using two BGP resource modules to configure a Cisco network device. We will be using the bgp_global module, which was covered in Rohit’s blog post, and the bgp_address_family module. The BGP configuration is split between these two separate modules to simplify configuration and data models associated with them.
Let’s start with a data model:
bgp_global:
as_number: '65000'
bgp:
log_neighbor_changes: true
router_id:
address: 192.168.1.1
neighbor:
- activate: true
address: 10.200.200.2
remote_as: 65001
bgp_address_family:
address_family:
- afi: ipv4
neighbor:
- activate: true
address: 10.200.200.2
network:
- address: 10.25. Continue readingWithout any of its own hardware and most of its software heavy-lifting dedicated to front-end development, security, and broader AWS systems integration, the cloud giant could own the quantum computing user base.

Minh Ha left a lengthy comment to my There’s No Recipe for Success blog post, adding an interesting perspective of someone who had to work really hard to overcome coming from a third-world country.
Ivan, I happened to read “Deep Work: Rules for Focused Success in a Distracted World” recently so I can attest that it does provide some valuable advices on how to do things well. Some of the overarching themes are stay focused and cut off unnecessary noise/drain the shallow. The author also suggests removing your social media account if you can’t see how it add values to your work/business, as social media can create attention disorder, seen in many young kids these days.

If you wake up every morning stressed about going to work, chances are that you are working in a toxic environment. There are many signs of a toxic workplace including having rude coworkers, but things that you may be experiencing include depression, loss of focus, reduction in confidence, and even constant headaches.
The psychological explanation behind feeling depressed due to a toxic workplace is related to the fight or flight response of the body. When you put yourself under constantly stressful conditions, your body produces cortisol, testosterone, and norepinephrine in unhealthy quantities. As a result, you may find yourself wanting to burst into tears by 2pm at work.
While working in a toxic environment can be difficult, it is certainly not impossible. Until you find a suitable alternative for yourself, there are many ways to survive a toxic workplace – regardless of how bad the situation may be.
The biggest reason why your workplace is toxic is probably due to the coworkers. You may find yourself surrounded by selfish, judgmental, and manipulative individuals that you do not resonate with. But while a majority of your coworkers may be toxic, there Continue reading
Ethan Banks wrote the best one-line description of the crazy stuff we have to deal with in his When Stretching Layer Two, Separate Your Fate blog post:
No application should be tightly coupled to an IP address. This common issue should really be solved by application architects rebuilding the app properly instead of continuing like it’s 1999 while screaming YOLO.
Not that his (or my) take on indisputable facts would change anything… At least we can still enjoy a good rant ;)
