Hello.

Statistically speaking, your ISP is the problem. 90% of the time, problems like this are the ISP. The other 10% of the time, though, it's something else - so you can't say *for sure* it's an ISP issue.

Also, based on your description, pinging from the outside shows something inside your network as the problem, and pinging from the inside to the outside shows something *outside* your network as the problem. This indicates it's the border between your network and outside - your ISP again.

On your google trace there, it looks like you focused just on 10 lost samples - and during that period, none of the downstream hops responded either. That indicates a problem with the connection between your network and outside (your ISP again).

Looks like an ISP problem, although you'd be better served by showing a whole route - looking at a few hundred samples, and then turning on the time graph for hop 1, hop 2 and for the final destination to show that the packet loss from the final destination is being introduced at hop 2 (the ISP).
