<p class="MsoNormal">We utilize a RX-4 with 10gbit uplinks. We
have a 10gbit Atrato and a 10gbit DC blend.

<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>
