<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>
