Internet becomes unusable for all other purposes when running cloud backup.  Cloud backups are very slow.


Before starting a backup to the cloud I start three pings in different command windows on my workstation.

//COMCAST DNS
PING 75.75.75.75 -n 1000  

//GOOGLE
PING 8.8.8.8 -n 1000


//My Gateway before Modem
PING 10.0.0.1 -n 1000


Internal pings come back in about 10ms with 0% loss.

Pings to the external IPs have 0% loss.

I launch the Cloud backup solution.  My internal pings remain constant.  All external pings begin to look like this.

Conducting the same test with a workstation connected outside our network into the cable modem creates similar Request Timed Out.

Are the "Request timed out" responses an indication of a Comcast network issue or is this normal?

Is the climbing ping response time normal?
