[bitfolk] Network drops

Hi everyone, I'm experiencing some strange network drops (or perhaps "pauses") on my VPS. Network traffic seems to be stopped for a few seconds (~15-30 secs) These seem to happen every few minutes. This seems to have started over the last couple of days and affect all network traffic AFAICT. (Certainly HTTP and SSH are disrupted.) There's no loading issues or memory issues that I can see. Has anyone else been experiencing similar? Next step is to run tcpdump to "capture" one of these pauses. Thanks, Tony
