Yeah we get major problems in a top 2 cloud provider where our on prem to cloud link dropped packets. We narrowed it down with iperf to the packet loss only happening on some ephemeral source ports. Ports were always ok, or always slow. Destroyed and recreated the cloud gateways and all was well. Should say another engineer figured it out. Cloud provider tried to blame our side. They did not excel at operations...
- toast0 6y agoYep, I wrote the tool to help narrow down network problems at our bare metal hosting provider. Our system used lots of long lasting TCP connections, 1:1 between systems; persistent packet loss was problematic. For some reason, they wouldn't let me have access to router link stats ;)
