broken pipes and closed connections

I'm having difficulty using my linode properly. Sessions are not staying alive, making it impossible to use with ssh or playing minecraft.
The webservices are ok though.

I have two mtr reports from two independent sources:

Is there something I should do with my linode to improve connectivity or is there something you can fix?

Im running ubuntu
I've tried turning off the firewall, changed tcp keepalive and sshd keepalive settings to no avail.
