<p class="MsoNormal"><span style="color:#1f497d">Hi Marius,</span></p>
<p class="MsoNormal"><span style="color:#1f497d"> </span></p>
<p class="MsoNormal"><span style="color:#1f497d">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.</span></p>

<p class="MsoNormal"><span lang="EN-US">Hoping someone could push me in the right direction, we have a rack in NextDC B1.</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">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.</span></p>
<p class="MsoNormal"><span lang="EN-US"> </span></p>
<p class="MsoNormal"><span lang="EN-US">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</span></p>
