Happy birthday to ARPANET, the forerunner of the modern internet! 53 years ago, the first message was sent over this pioneering network, paving the way for a world of interconnection and innovation.

As a tech enthusiast, I am constantly amazed by the ways the internet has transformed our lives, allowing us to communicate, learn and share ideas across boundaries and borders. From social media to e-commerce, from telemedicine to remote work, the internet has become an essential part of our daily routines, enabling us to connect with others and access a wealth of information at our fingertips.

This morning, I took my wife to the hospital for routine blood tests that had been scheduled for some time. Everything was going smoothly: check-in, number, waiting room. Suddenly, everything came to a halt and shut down. I was connected to the hospital’s public Wi-Fi and noticed that my connection also went down.

Having managed a couple of similar facilities, I immediately understood what had happened. I saw the staff panicking and calling the technicians, but they quickly reorganized within 10 minutes. They managed to process everyone who already had a number and then proceeded with the others in the order of their arrival. Despite the ten-minute delay (even though people started complaining right away), they were extremely efficient.

I later confirmed that the entire booking, check-in, and queue system is “in the cloud.” The hospital experienced a connectivity interruption, and all related services stopped. The staff no longer had access to anything, so a technician sent the lists to a manager via another channel, and everything resumed manually.

For years, I’ve insisted that certain things MUST be local. The healthcare facilities I manage have all the necessary systems for the operation of the facility internally, including patient records. External services like websites, emails, etc., are secondary.

Everything essential must always be accessible locally and, in special cases, it should be possible to physically access the servers and connect directly to them, bypassing any network/switch failures.

There has been only one interruption in the past, due to human error. Today, we have redundant servers (not HA on virtualizers, but two machines running the same software with replicated databases - on separate power lines) so such an issue shouldn’t happen anymore.

Not everything can be anticipated, but history is a great teacher. The Internet connection will eventually be interrupted :-)

When it comes to the health and survival of people, there are no compromises.

Say it with me...
Network vulnerability!!!

A quick story/rant.. my cousin got my mother a new coffee maker. I don't expect my mom to use the WiFi functionality, but I'm still concerned about why we would need a whole coffee maker to have a small computer in it... I understand the versatility of not having a hub, and that hubs are also a single point of access for any malicious actors, but I'm sure a hub for multiple devices instead of a thing for a coffee maker would be updated much more frequently, and supported for longer.
If nothing else, maybe I can pull it into my janky Home Assistant setup somehow.

Even if it doesn't end up being a gateway for snooping on home network, it is quite silly, in my opinion.
Now, I must go check to see if anyone's hacked at these yet lol...

This article (cited on Slashdot) suggests that the policy decision by Amazon Web Services to charge for IPv4 addresses could accelerate migration to IPv6.
My ISPs (both cable and mobile) support IPv6, as does my server's hosting provider, so I personally made the switch to a dual-stack configuration quite some time ago. Those who haven't (and who use AWS) now have an additional financial incentive.

This article introduces the new L4S standard (RFC 9331) for addressing Internet congestion issues, specifically, buffers on networking devices. It appears to be a congestion notification mehcanism. Presumably it is superior to the queuing algorithms implemented on routers. My OpenWRT router, for example, offers a choice of queuing algorithm.

I wrote a bot that parses the current #Mastodon instances and assigns them to the respective #ASN (de.wikipedia.org/wiki/ASN).

Interesting is the concentration on a few top ASN. Here for example the 10 most frequent ASNs as Pie Chart (as of 11/25/2022).

❤️ Thanks to @TheKinrar for the nice API for receiving the current mastodon instances.

Linux really needs to remove the “privileged ports” security theater bullshit.

We’re no longer living in the mainframe era. The security properties of the Internet are different to mainframes. This is actually an anti-feature that either complicates life or actually compromises security (when folks run servers as root and forget to drop privileges , etc.).

If anyone has any sway within the kernel team, etc., please do your thing.
