Or proxy it.
I have public mirror of Devuan on my overseas server, and my ISP has a public mirror of Debian, which is quota free for me. Since most of Devuan is unadulterated Debian, some of the mirrors just redirect to Debian mirrors for those parts. I proxy most of my web stuff through that overseas server. It has a special rule to redirect requests for Debian packages that come from my home IP, to my ISPs Debian mirror. I'm fairly sure my ISP knows what my home IP is. They can probably guess what my servers IP is, but I don't care.
