Packet loss is now making my Hetzner box almost unusable. Does anyone know much about mitigating this?
About a month ago I started getting massive packet loss between my residence in Texas and my Hetzner box in Falkenstein. Wireshark shows lots of TCP Out-Of-Order
and TCP Dup ACK
and most of the time I get less than 1Mbit throughput Hetzner to Texas. The traceroute goes from Heztner, telia.net
, and then Comcast. Outbound from Texas goes through core-backbone
.
I tried playing with TCP Window memory size and it didn’t help and I don’t think that’s the issue anyway after looking at other long distance connections that work without problems.
To confuse things further, I get 100Mbit from Hetzner Helsinki without problems. The IPv4 traceroute to there is via telia.net
and I have almost no packet problems, and IPv6 is via core-backbone
with lots of packet loss but evidently not enough that’s noticeable and throughput is still 100Mbit +.
So I don’t know what else to try and I’d hate to give up my Hetzner box in Falkenstein because it’s been great and very cheap for over a year now. And it used to work great for streaming and even a slightly laggy desktop VM or two.
Anyone got any ideas to resolve this? Or is it just “Well, that’s the internet. Tough luck.”
