We have this same cloud disconnect issue as well and all are not feeding the cloud using the same services --- different ISP's involved. We've had this problem since the very beginning. As Christopher eluded to, it can great an unnecessary panic that something is wrong. For this reason we no longer use notifications for cloud because it is mostly false alarms.
Yes...it doesn't mean the link(s) are necessarily down, but it does negate the full value of the cloud functionality for us and perhaps others.
Are there any plans to make the cloud side more stable in this aspect?
