Hello! My main goal with this post is to get ideas of what to look into, I am not asking for a free IT consultation (but if anyone were kind enough to want to, I wouldn’t turn them down). The only important things you need to know are that my machine runs the newest Debian, my upload speed has said and still says 800 mb/s, it’s wired over ethernet, I use Caddy, I live in an apartment with CGNAT, and it’s ipv6 only.

​

My server used to be reliable enough that I was able to stream video while in Japan from my server in the US, but now I can’t even ssh into it from outside my wifi (but it’s blazingly fast while in the local link scope). I still can ping it, but the pings are shockingly bad. It’s technically sending data, but so slowly it might as well not be. I haven’t particularly touched any configs for a while and I don’t know what to even look up

​

Thanks for your time!

TL;DR - server used to be fast, still says it is, but now it’s very slow, I want to know what to look into not step by step help

    If you had old traceroutes, i would compare the path it is taking and see what is different about it.

    I would also use traceroutes to see if maybe there is packet loss at one of the endpoints along the path. I’m not sure if there is something like pingplotter for unix, but a tool similar to that would potentially be helpful
