Are you saying that all of your interfaces on the PA-220 were offline when the ISP connection went down, or was it just your untrust interface that went down with the ISP connection?


If there was an issue with your ISP connection the untrust (or whatever you use as an internet zone) interface going down might make sense depending on the nature of the ISP issue, but loosing the other interfaces at the same time doesn't make sense. Are you sure it was an ISP issue and not an issue with the dataplane on your PA-220?
