[AusNOG] Latency Issue

Tue Aug 2 08:10:27 EST 2016

Web pages seems to timeout on first load attempt sometimes. Refresh and jumps through ok. Once loaded no issues at all. Just wondering if this could cause it or something else in the works

Hi Marius,

Are you seeing “real world” traffic or performance issues, or only on the traceroute? A lot of routers dedicate resources to throughput rather than responding to ICMP, so it could be the specific hardware on AAPT’s network or their configuration. The fact that the later hops have consistent ping times, including all 3 paths being within 1ms of each other for the last hop, implies that traffic is flowing ok.

Hi All,

Hoping someone could push me in the right direction, we have a rack in NextDC B1.

I am getting some strange latency issues when doing trace routes, we have 2 x BGP routes through AAPT, each one on a different AG Access, and also 1 BGP with Pipe networks.

Issue seems to be on the AAPT stuff, ping doesn’t seem so spike a lot but the traceroute is really an issue as sometimes it will actually timeout. Anyone ever seen this or have some guidance? Below is some logs
