Thanks!

Do you see improvement with https://one.one.one.one/ installed, please?

I just checked it and there are no more packet drops to cloudflare.
I see that the incident has been resolved.

Latency is now back at normal. WARP is also now stable, earlier it used to disconnect frequently.

Thanks!
