I wanted to download install Ubuntu 26.04 today and found out that Ubuntu was undergoing a DDoS attack, making their main website inaccessible. I was a bit surprised that they didn’t have a DDoS protection service on their main infrastructure (or perhaps it was overrun too), and I assume they’re going to sort that out going forward, however, I couldn’t find any reasonable ways to get the ISO files I needed until I came across the BitTorrent links:

You need to know exactly what image you need, which for most people is usually the one that ends with “-desktop-amd64.iso“. The prefix is usually the build, such as “ubuntu“, “kubuntu” etc, followed by the version, which for me was “26.04“.
I ended up downloading ubuntu-26.04-desktop-amd64.iso and loading it up in my torrent client, which completed in no time, only a few seconds slower than a standard https download might have.
You also need a BitTorrent client such as: https://transmissionbt.com/download
