Back in ...huh maybe late 2002, we were testing embedded machines for surveillance video streaming through the then new UMTS 3G system. So we had this very compact (there were no Raspberry PIs back then) Linux machine with its PCMCIA 3G card which would use ffmpeg to stream the video taken by a camera, to a nearby broadband connected PC having a fixed IP. Everything worked, but we were literally struggling to achieve low latencies because the application would have been in potentially life threatening scenarios; the customer had been very clear about the numbers: half a second maximum latency, not more. We were almost getting there, with some quality tradeoffs, still something was slowing us down, so we fired a traceroute to see the path traveled by our precious video packets, and the shock when we found that to reach a machine on the same bench they went through not one but two countries to get to London, and back. We filed a detailed request to the carrier, which was our partner, to ask if there was something wrong with routing. We got no reply, other than realizing the following days that they had blocked ICMP and other things so that we couldn't use traceroute anymore.

Hahaha yeh same here. People thinking I was mad talking about it until Snowden came around
