Good day. I have a problem downloading files that have not been cached from the VIE data center. Sometimes it manages to download part of the file at normal speed, but after a while the speed drops below 1 MB/s. When the file is cached, it downloads normally. However, when I download from the FRA data center, which is also not cached, the download speed is around 30 MB/s.
For example, I sometimes like to download albums from Bandcamp; there are many files there that have not been cached.
As part of my testing, I’m testing this on two DNS: my ISP, which runs on my FRA datacenter, and from NextDNS, which runs on my VIE. I performed the tests around 7 pm UTC+1.
DNS from my ISP:

I am not sure if this is a problem with my connection or if it is a datacenter problem.
