Hello, your DNS have a little problem at my location, Buenos Aires. See below:
root@OpenWrt:~# nslookup download.windowsupdate com 1.1.1.1
Server: 1.1.1.1
Address 1: 1.1.1.1 1dot1dot1dot1.Cloudflare-dns com
Name: download.windowsupdate com
Address 1: 2800:240:f::be62:989a
Address 2: 190.98.152.25
Address 3: 190.98.152.32
These IP is from Telefonica International Carrier (slow, non IXP, and expensive traffic).
EDIT: today gives 13.107.4.50 (Microsoft Brazil) and 192.16.48.200 (Verizon CDN). It’s OK.
Meanwhile in other DNS:

Can you fix it? I do not want to make international traffic downloading updates. Thanks to be the first big DNS allocated in my country.
