Can’t wait for all the network and social media graph analysis about the impacts of the tandem data centers being hit. Right now it seems anecdotal, but soon it should be more specific.

Network security question: How are people restricting outbound connections based on DNS names? For example: Server A wants to connect to cdn.network.com, and that can resolve to a huge range of IPs, so not feasible to allow list all possible outbound connections. I vaguely remember some dns […]

Arti 2.6.0 released
Arti is our ongoing project to create a next-generation Tor implementation in Rust. We're happy to announce the latest release, Arti 2.6.0. This release continues our ongoing development towards using Arti as a relay and as a directory authority, with much of the work focusing on document parsing, directory mirror support, and DNS stream handling. Additionally, on the RPC front, we are making steady progress towards RPC-based configuration management. Finally, congestion control and Counter Galois Onion cryptography are both now always enabled in `arti`. As usual, there also are many under-the-hood improvements to our infrastructure, testing, and documentation, along with multiple bug fixes and internal cleanups. For full details on what we've done, including API changes, and for information about many more minor and less-visible changes, please see the CHANGELOG. For more information on using Arti, see our top-level README, and the documentation for the `arti` binary. Thanks to everybody who's contributed to this release, including Andrew Kloet, Steven Masnada, iqdecay, pryty26, steven. Also, our deep thanks to our sponsors for funding the development of Arti! * announcements * releases
