Networking notes for July 2026
Researchers at Foundation Bruno Kessler in Italy have collected 50 million TLS sessions established by computers in their institution to analyze the different versions of TLS that are currently used. Their technical report provides interesting insights on the deployed TLS implementations.
Interesting analysis of the public peerings deployed at IXPs. Akamai leads with 79 Tbps of capacity, three times more than Google.
Nice animation showing the deployment of Starlink terminals in Europe during the last five years.
A very detailed discussion on how to setup your own email server. Over the years, with the growth of spam and other email related problems, running an email server has been more and more difficult. As the Internet is a decentralized system, this is a very good exercise for students willing to learn or to operate real production servers.
The Unicode consortium regularly discusses proposals for new characters. This includes various emojis. Charlotte Eiffel Lilith Buff maintains a list of all rejected emojis.
RFC10008 describes the new QUERY method for the HTTP protocol. This method should in the coming years replace the existing usage of GET or POST to send a request with queried values to a specific server. This is also the first published RFC whose number is above 10000!
RFC9958 provides a clear description of post quantum cryptography for network and protocol engineers.
Interesting discussion in IEEE Spectrum with various examples showing how our smartphones, connected cars and other devices collect data that is often requested by police officers.
In the USA, 5G Fixed Wireless Access (FWA) already serves more than 14 million customers. This becomes a widespread Internet access technology, next to xDSL, cable, fiber and satellite.
A problem with the time service caused a huge outage in the Telstra network in Australia when it went back in time to November 2006.
Doug Madory provides a closer look at the impact of World Cup football matches on Internet traffic.
