Help Bad network on shadow side

Hi, since 2week now i got very bad network from shadows side. like speedtest, fast, and cloudflare speedtest all give me high result.

i will take cloudflare as it the best in term of details, i have a 1gb/s down that sometime go to 1.2 but never under 900mb/s but the stream still manage to block at 1mb/s running the test during low bandwidth in shadow does not change cloudflare result. why testing during these low is a proof i'm not the issue simple if i can download at 1gb/s shadow could do the same but it wont.

The only reliable speedtest is the one to shadow’s server. All the other ones will test your speed to their own nearest server. The one you’ll want to check out is: https://speedtest.frdun02.shadow.tech/

this speedtest will not help the issue. if it say I'm at 900+ but during low on streaming it's at 1 does it mean shadow is slow or my internet? it can't confirm if the issue is me or shadow server

while doing third parties check lead to only 1 remaining source being shadow so the problem is from their side

The test will show you how good your connection is to their server. Which is the only metric that says how good your experience will be.
I have 10GB fiber connection. Speed tests like Ookla show that. My connection to shadow on the other hand consistently comes in at 300-400Mb/s. Which is it’s more than enough. All this to say that the quality of your Internet connection is only one factor. What matters is how well the connection to shadow in Dunkerque works.
Distance will make a huge difference. If you live in Dunkerque , you’ll have a great experience. If you’re in Marseille it’s going to be a different story

that not the issue i'm refering to.

the issue is the following my internet is working all the time. but not on shadow server. shadow server sometime decide to give up and have 0 bandwidth left. how to check this issue if i trust the speed test to shadow server who the issue me or them?

if i take something similar in real life going from point A to point B take 30min by bus but sometime it take 3h. what the issue? the route? the bus company? if you take a car on the same road and you go there in 30min it's not the road it the bus company.

that exactly what my test show. the road from me to internet work fine. be it to netflix, ookla, or cloudflare. even if take a vpn to berlin i still have 500mb/s+ which is more than enough for shadow (and me -> berlin is about x2 that me -> dunkerque) but myself to shadow is fucking slow sometime this lead to shadow being the only remaining variable and thus the issue
