Some academics tried to get Czechoslovakia to join up with the European Academic Research Network (EARN), a network similar to the internet, in 1987, but the then-communist government opposed the idea of sharing research with the west. Interest began again after the fall of the Iron Curtain. An IBM mainframe computer was installed in ČVUT in 1991. It connected to the EARN network via a landline link to Linz, Austria, at a speed of 9.6 kbps. This was a mere trickle compared to the average speeds today of 25 Mbps, over 2,000 times faster.
