Comment Verizon et un optimiseur BGP ont affecté de nombreuses partie d’Internet aujourd’hu

Aujourd'hui à 10h30 UTC, Internet a connu une sorte de mini crise cardiaque. Une petite entreprise du nord de la Pennsylvanie est devenue le chemin privilégié de nombreuses routes Internet à cause de Verizon (AS701), un important fournisseur de transit Internet. C’est un peu comme si Waze venait à diriger le trafic d’une autoroute complète vers une petite rue de quartier : de nombreux sites Web sur Cloudflare et beaucoup d’autres fournisseurs étaient indisponibles depuis une grande partie du réseau. Cet incident n'aurait jamais dû arriver, car Verizon n'aurait jamais dû transmettre ces itinéraires au reste d’Internet. Pour en comprendre les raisons, lisez la suite de cet article.

Nous avons déjà écrit un certain nombre d’articles par le passé sur ces événements malheureux qui sont plus fréquents qu’on ne le pense. Cette fois, les effets ont pu être observés dans le monde entier. Aujourd’hui, le problème a été aggravé par l’implication d’un produit « Optimiseur BGP » de Noction. Ce produit dispose d’une fonctionnalité qui permet de diviser les préfixes IP reçus en parties contributives plus petites (appelées « Continue reading

Today is a bit of a sad day for Network Collective…

It’s with quite a heavy heart that that I’m announcing that Russ White and Eyvonne Sharp are both stepping away from organizational responsibilities at Network Collective. There is no question that this is a significant loss on both accounts. Both Russ and Eyvonne have played irreplaceable roles in building Network Collective into what it is today, and those contributions cannot be understated. I’m grateful for every ounce of effort, wisdom, and perspective that they have invested into the podcast and wish nothing but success to the both of them as they move into new endeavors. Luckily both will still be around in the member’s slack and hopefully on a show or two every once in a while!

What does this mean for Network Collective?

First, Network Collective as you know it isn’t going anywhere. Clearly, I’m going to have to take a step back and evaluate how things proceed from here. We’ve made many plans with the intention of three active contributors and now that’s simply not the case. You might notice some blips in the production schedule and changes to the lineup of podcasts as I get things rearranged and streamlined for a one-person shop.

First-hand Feedback: ipSpace.net Network Automation Course

Daniel Teycheney attended the Spring 2019 Building Network Automation Solutions online course and sent me this feedback after completing it (and creating some interesting real-life solutions on the way):

I spent a bit of time the other day reflecting on how much I’ve learn’t from the course in terms of technical skills and the amount I’ve learned has been great. I literally no idea about things like Git, Jinja2, CI testing, reading YAML files and had only briefly seen Ansible before.

I’m not an expert now, but I understand these things and have real practical experience on these subjects which has given me great confidence to push on and keep getting better.

The Internet Is Your Oyster: MANRS at International Telecoms Week

What do oysters, clams, and mussels have in common with network operators? Hint: it’s not just that they are both in Atlanta this week, either in exhibits in the Georgia Aquarium or for the 2019 International Telecoms Week.

It’s that both bivalves and network operators play an incredibly important role for their ecosystems: they filter the bad stuff out and leave things a lot cleaner.

As water quality is vital to life in the ocean, the global routing system is vital to the smooth functioning of the Internet. The routing system’s decentralized structure, made up of thousands of independent networks tied together through business decisions and trusted relationships, provides flexibility, scalability, and overall durability.

However, despite its strengths, thousands of routing incidents occur every year. Some of these can be pretty scary, with route hijacks sending government traffic through the networks of foreign adversaries; route leaks slowing parts of the global Internet to a crawl; or hackers using spoofed traffic to take down websites in distributed denial of service (DDoS) attacks.

Network operators can help mitigate these problems by using stronger filtering policies to block spoofed traffic coming from their networks (helping guard against DDoS attacks) and filter route announcements Continue reading

The Week in Internet News: AI and IoT Could Lead to Industry 4.0

The new revolution: Advances in the Internet of Things and Artificial Intelligence are leading to a fourth industrial revolution, Ars Technica suggests. This so-called Industry 4.0 represents “huge changes in much of the technology we deal with in our daily lives. Some of those changes have been for the better, making our interaction with machines and information more natural and more powerful. Others have helped companies tap into consumers’ relationships, behaviors, locations and innermost thoughts in powerful and often disturbing ways.”

Security gaps: But all is not well in IoT land. Legacy problems related to networking technologies are making IoT security “as bad as it gets,” IoT Hub reports. In addition, staff remotely monitoring IoT sensors don’t have the experience to fix problems.

They’re keeping their eyes on you: The Indian government has found a way to track WhatsApp messages without breaking encryption, Business Insider reports. The surveillance technique involves the government asking the Facebook-owned messaging platform to implement an identifier that would allow law enforcement officials to pinpoint who sent the message without reading it.

A new way to pay: In other Facebook-related news, the company is planning to launch a new cryptocurrency called Libra, The Verge Continue reading

Fast key-value stores: an idea whose time has come and gone

Fast key-value stores: an idea whose time has come and gone Adya et al., HotOS’19

No controversy here! Adya et al. would like you to stop using Memcached and Redis, and start building 11-factor apps. Factor VI in the 12-factor app manifesto, “Execute the app as one or more stateless processes,” to be dropped and replaced with “Execute the app as one or more stateful processes.”

It all makes for a highly engaging position paper (even if that engagement doesn’t necessarily take the form of agreement on all points)! It’s healthy to challenge the status-quo from time to time…

Remote, in-memory key-value (RInK) stores such as Memcached and Redis are widely used in industry and are an active area of academic research. Coupled with stateless application servers to execute business logic and a database-like system to provide persistent storage, they form a core component of popular data center service archictectures. We argue that the time of the RInK store has come and and gone…

What on earth are they thinking? ;)

Why are developers using RInK systems as part of their design? Generally to cache data (including non-persistent data that never sees a backing store), to share Continue reading

Gitlab Gitaly Error

After a power failure of the instance hosting my gitlab server I began getting errors when trying to access existing projects (404) or create new projects (503) from the web interface. I could see the list of projects but if I clicked on the link to any of them I would get a 404 errors. ...

Major Updates to Cisco Certifications Part IIII (CCIE)

The CCIE, now 25 years old, has always been the pinnacle of Cisco certifications. There has been a lot of buzz on the importance of certs, and the CCIE, in the “new” era. For that reason, it’s more important than ever that the CCIE gets updated and stays current.

With Cisco’s new announcements, what is changing with the CCIE?

The first thing to mention, for those that already have a CCIE, is that the recert cycle is now being changed to match the other certs such as CCNA and CCNP, so that the recert cycle is 3 years. This means that the suspended status is gone. The cert is now valid for 3 years and there is no suspended status. This means that you need to keep track of your date because there is no “grace period”, after 3 years, if you miss to recert, you’re out! This also means that effective 24 February 2020, if you are still active or suspended, you get an extra year “for free” and you will be a active CCIE to your new expiration date.

Because the recert cycle is now 3 years, you will need to get 120 CE credits instead of 100, Continue reading

Musing: HPE Cloudless Is A Good Marketing Joke

HPE announced a marketing campaign built around the idea of Cloudless. I see this as a superb bit of trolling as the cloudista faithful have been delightfully duped into talking about HPE and highlighting how narrow minded they are. Most of them don’t even realise just how hard they are being rick-rolled here. Its bloody […]
