As someone living in Slovenia and still running on ADSL2+ I'm jelly. Regarding your 20/20, highly suspect, it's likely you were doing speedtest tests against your ISPs server which would make sense but you would never get that past their gateway.
I wasn't doing speedtests though, I was running torrents 24/7. High school was fun like that. Torrents were the only way to get music, movies, and TV shows back then.
