Bandwidth requirements

Hello, I currently have my own mirror available at https://archmirror.polarian.dev which I use for my hosting, as I have many VM's and LXC containers which other people also use therefore having a complete mirror is useful to allow for high speed package installation, and prevents load on other mirrors constantly updating multiple identical packages across all containers and virtual machines. I am limited by bandwidth however, as it is a home server, with down of 80mbps and 20mbps up on average, and on the archwiki page it is highly unadviced to contribute to the mirrors if you do not have at least 100mbps upload. I would still like to contribute, but not sure how. Polarian
