Passionate about networking protocols, the Internet, how to measure it and big data. Overall a curious mind and problem solver.

I'm frequently despondent when I see organizations remove or hide once public Internet operational status and trending data.

At one time, lots of networks used to publish a variety of status and traffic summaries. The non-profit Internet2 for example was exemplary in this regard. Cloudflare, a commercial organization, now provides far more public benefit data than they do.

A big loss earlier this year was the once public Equinix network status page - https://community.equinix.com/blog/videostutorials/introducing-equinix-status/519

As the Internet becomes increasingly complex and inconsistency abounds, having access to trends and data from diverse vantage points is as important as ever, but unfortunately increasingly difficult to get.

Anyone else here who can confirm a 504 - Gateway Time-out on spoofer.caida.org? Tried to access it various times today, but it just times out every time.

#Outage #CAIDA #Spoofing #Downtime

Hi all. It's been a while since I've asked, but I'm here again asking for you to support your local fediverse instance. I know many instance operators struggle to make ends meet each month, and there does seem to be a downward trend on donations across the board. If you love this place and are in a position to and your instance supports it, please consider supporting them.

Thank you!

For people who are monitoring the outages in Iran, I encourage you to read through this thread of observations about #I2P router health in the region. https://bsky.app/profile/np-tokumei.net/post/3lsdh7lwby22i

Thank you so much to Phong for continuing to maintain this resource and for providing more insight into this outage.

🧵1/ Interesting observations about @geti2p.bsky.social access disruptions in Iran — I’d like to add to this based on measurements from i2p-metrics.np-tokumei.net, a system I built several years ago to collect I2P Metrics, supported by @opentechfund.bsky.social Here’s what the 🇮🇷 Iran data shows: 📉👇 [contains quote post or other embedded content]

@jerry - before it is misunderstood: I am aiming for global blocking of spam accounts and AI generated content. It should not address obvious human accounts.

Hey, @jerry , by any chance, does a #Mastodon administrator have access to a ranked list of #blocked #accounts by its users?

A cool idea would be to have a #cleanuptuesday or the likes where the most blocked accounts/instances are tooted about and democratically decided to be globally blocked a day later? "Most blocked" as in most blocked by #infosecexchange users, of course.

Is there any great book on #AlpineLinux ? I love the concept, and love the considerations of the operating system. Yet, I usually opt for #Debian since I am much more familiar with it. It would be great to change that in the mid-term.

A great write-up by @quux on the new #DNS4EU resolver: How much EU is in DNS4EU?.

The final statement is tough: "And then there is the issue of being single homed."

But wait a second, AS60068 sounds familiar. It's Datacamp Limited, which operates #CDN77. Yes, the announced prefix appears to be single-homed, but it peers to a CDN.

Nevertheless, my understanding is that an instance of DNS4EU will be hosted in various service provider networks, right? Given that, I would assume that the project by now is just in an early stage?

Curious about a short public discourse :)

How much EU is in DNS4EU?

This is another post that started after several toots on mastodon. Most of the things presented here were already tooted by other people, but I think this is a good chance to write a mini tutorial about what to look at. We’ll use DNS, whois, BGP and your favourite search engine. What is DNS4EU? To quote the web page: Supported by the European Union Agency for Cybersecurity (ENISA), the European Union’s DNS4EU secure-infrastructure project provides a protective, privacy-compliant, and resilient DNS service to strengthen digital sovereignty and security for EU citizens, governments, and critical infrastructure.

Ever dreamed of running an LLM on a Raspberry Pi, like the good old days of hacking? Check out our blog on how these tiny computers stack up in LLM performance. #cybersecurity #LLMs #AI

Exploring #DNS4EU a little further and throwing myself back to research I was involved in a while back (https://arxiv.org/abs/2403.05638), surprisingly shows that the #European #resolver shows no problems resolving the sanctioned entities of #RussiaToday and #Sputniknews.

An oversight? I would be less surprised if the unfiltered #resolvers resolve the domain names, but even the protective ones resolve to the correct domain names, revealing that #DNSblocking is not applied on #EU cyber-resiliency flagship project.

Internet Sanctions on Russian Media: Actions and Effects

As a response to the Russian aggression against Ukraine, the European Union (EU), through the notion of "digital sovereignty", imposed sanctions on organizations and individuals affiliated with the Russian Federation that prohibit broadcasting content, including online distribution. In this paper, we interrogate the implementation of these sanctions and interpret them as a means to translate the union of states' governmental edicts into effective technical countermeasures. Through longitudinal traffic analysis, we construct an understanding of how ISPs in different EU countries attempted to enforce these sanctions, and compare these implementations to similar measures in other western countries. We find a wide variation of blocking coverage, both internationally and within individual member states. We draw the conclusion that digital sovereignty through sanctions in the EU has a concrete but distinctly limited impact on information flows.
