T1 ?
In the late 90's early 2000's I used to work for a "big cyber security" partner and we had access to their network, which was a reasonable 4mbps, due to firewalling we heard ... we could even reach the internet via it but it felt like a 56k modem. Then, one day, it was lightning fast, we checked the internet, and it was lightning fast, too, about 8 times faster than our corporate internet access. It took "big cyber security" months to realize all the data poring through to this partner's network ... I had great trouble, and no authority, keeping the team off p2p - my boss was the hardest abuser ... he literally filled several 4Gb drives with mp3's and mpg's, swapping them out as he went along, his download queues were impressive.
