I understand that's part of it, but I have been given to believe* also hardware gating logic and software which both intercepts and has the effect of intercepting packets.

Incidentally, do you know about the Canadian anti-throttling case? Runs pretty much on the same lines as here, although different legal procedures.

On two known servers, client and host separated by distance, send a stream of packets with a loop-back to return them. A reasonable size PDF would suffice as data. If either server log contains 307s then something is picking up packets, redirecting elsewhere and returning to continue the stream. Also, emanate a series of consistent pings from both ends. A long identical delay in a particular node across pings will display interception. If both logs, client/server/client and loop-back streaming, show the same results then you have proof of interception. To corroborate this proof, try the same client/server test with either a VPN or secure HTTPS connection: if the delaying node no longer delays you substantiate HTTP interception. You could go further with such forensic tests and analysis but these simple methods will prove the case.
