The Server is actually located in Germany and has a 2.5 Gbits upstream. On top of this, this website is set behind cloudflare, to cache the assets and others.
Generally, there is the complete cloudflare proxy enabled, but we are also forcing:
TLS 1.3
ECH is enabled as default for more security
If your browser supports zstd compression, then it will use this
Some ISP’s like the german telekom has a bad routing to cloudflare. You can check, to which cloudflare servers youre connected with the cloudflare optics addon, see the screenshot.
Maybe try to use a different nameserver, like cloudflare/google or equal.
I have 1gbps connection with nextdns (doh). It’s fast everywhere, here is fast too.
But like I said, sometimes there is this cold boot/start like behavior that takes many seconds till the website are acessible. Once it is, it’s continously, till I stop for a time.
