• Noah Meyerhans: Determining Network Online Status of Dualstack Cloud VMs

  When a Debian cloud VM boots, it typically runs cloud-init at various points in the boot process.

  Caching is the invisible backbone of the web. It’s what makes sites feel fast, reliable, and affordable to run. Done well, it slashes latency, reduces server load, and allows even fragile infrastructure to withstand sudden spikes in demand. Done poorly – or ignored entirely – it leaves websites slow, fragile, and expensive.

• Jan Wildeboer ☛ My Own DNS Server At Home - Part 1: IPv4

  “It’s always DNS” is a famous meme among network people. Name resolution is technically quite simple. It’s “just” translating a hostname like jan.wildeboer.net to an IP address.
