<p class="MsoNormal">Not totally sure where to start on this, so maybe someone can help.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We utilize a RX-4 with 10gbit uplinks. We have a 10gbit Atrato and a 10gbit DC blend.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Long story short, each server is connected to a router with 10gbit of connectivity at the router level, and 1gbit switch ports to the server. Each service should be able to pull on average 60M/s on a cachefly test.<o:p></o:p></p>
<p class="MsoNormal"><br>
Last month or so, VPS have randomly begun throttling themselves. A container currently is only able to pull 772K/s on the same speedtest a container on the same node can pull normally at 60, and the node can pull fine at 60-80. If I REBOOT the router, change
the container’s IP, or migrate the container to a different hardware node, the issue is fixed temporarily – eventually it starts doing it again. It happens at random, in no particular order, and we haven’t been able to determine WHAT causes this to happen.<o:p></o:p></p>
