Continued outages and drops of service

I have some of my services in the cloud, and some of them running from my dedicated comcast businesss connection.  I have the cloud servers monitoring themselves and my comcast connection.  I have noticed several times when working from the comcast connection, and from externally that my service has dropped.  I have proof of this (attached) happening TWICE within the last two hours.  Also - the "gateway" that I reference isn't my device, but the IP of the leased hardware.  The times in he graph are central times.
