How to avoid blacklisting droplets due to constant heavy network usage

Posted on October 20, 2016

Hello DO,

After some struggle finding info about DO’s networking specifics , I was able to find this statements:

  • Each physical hypervisor node has multiple 1Gbps network links (up and down).

  • These connections are shared by the droplets on the node

  • If your droplet is constantly above 300Mbps, sooner or later it will be blacklisted

We want to deploy our mobile backend services which have constant heavy network usage profile, so I was hoping you can give us few answers about how to stay safe on your infrastructure, while having some sane networking performance.

  • Are the droplets safe if we have many of them ( > 100 ) that are constantly using 290 Mbps ?

  • Can we go safely above 300Mbps with the private network ?

  • What happens if we hit a hypervisor that has 3 droplets already constantly using > 300 Mbps, is there any traffic shaping applied in that case ?

  • Is there any connection between the instance size and the 300Mbps limit
