Severe packet loss Amazon AWS->Telia

[Marian Ďurkovič]

Hi,

we're experiencing severe packet loss for downloads from Amazon AWS via Telia
network, tcpdump regularly shows multiple missing packets triggering SACKs like
this:

08:33:48.935415 IP 147.175.167.x.57668 > 54.231.33.x.443: Flags [.], ack
1051088, win 16384, options [nop,nop,sack 4
{1066840:1068272}{1063976:1065408}{1059680:1062544}{1056816:1058248}], length 0

Any ideas?

Thanks,

   M.
