The upgrade of the NSFNET backbone to T1 completes and the Internet starts to become more international with the connection of Canada, Denmark, Finland, France, Iceland, Norway and Sweden. In the US more regionals spring up - Los Nettos and CERFnet both in California. In addition, Fidonet, a popular traditional bulletin board system (BBS) joins the net. Dan Lynch organizes the first Interop commercial conference in San Jose for vendors whose TCP/IP products interoperate reliably. 50 companies make the cut and 5,000 networkers come to see it all running, to see what works, and to learn what doesn’t work. The US Government pronounces its OSI Profile (GOSIP) is to be supported in all products purchased for government use, and states that TCP/IP is an interim solution! The Morris WORM burrows on the Internet into 6,000 of the 60,000 hosts now on the network. This is the first worm experience and DARPA forms the Computer Emergency Response Team (CERT) to deal with future such incidents. CNRI obtains permission from the Federal Networking Council and from MCI to interconnect the commercial MCI Mail service to the Internet. This broke the barrier to carrying commercial traffic on the Internet backbone. By 1989 MCI Mail, OnTyme, Telemail and CompuServe had all interconnected their commercial email systems to the Internet and, in so doing, interconnected with each other for the first time. This was the start of commercial Internet services in the United States (and possibly the world).
