14.11 Group failed to respond to ping. ICMP ping request

Hi, Question, I'm getting this log event. [ID: 14.11] Group failed to respond to ping.  The group did not respond to an ICMP ping request. As well I see on our Hyper-v environment. Cluster Shared Volume *)') has entered a paused state because of '(c000020c)'. All I/O will temporarily be queued until a path to the volume is reestablished. it seems like it's recurring now on every Saturday morning. I have looked into our own backups, but nothing is running at that period in time. Is the PS6100 doing something then? I'm a bit confused....
