[bitfolk] Intermittent connectivity issues?

Hi, I'm not sure if there is a problem but for the last couple of months, I've been seeing about 1 NAGIOS alert a week and various VPN problems that seems to say that there may be intermittent connectivity issues within the cluster. I'm seeing SSH warnings most commonly that my VOS is uncontactable even though I was logged in during some of them. I had a 10 hour backup file age NAGIOS warning today. I've also recently seen my VPN dropping out much more frequently than usual. Has anybody else experienced any symptoms please or is it just me? Thanks, Paul.
