Initially, the CSU sites linked to CENIC’s network through interconnection between CalREN and 4CNet, the CSU network that already provided Internet services to all CSU campuses and the California Community Colleges. In 2000, the State of California provided funding to the University of California for the Digital California Project, which allowed K-12 schools to connect to CalREN. The University of California contracted with CENIC to develop and implement the project, with county offices of education as the primary connection points. Next, CENIC began to design a network architecture to support all educational institutions. In 2002, the CENIC board of directors decided to obtain fiber leases for the major north-south portion of the CalREN network, putting in place an architecture that continues to the present day. CENIC has continued to add more leased fiber to its network, and today CalREN operates over 8,000 miles of fiber. Between 2003 and 2005, CSU campuses and California Community Colleges were migrated from 4CNet to CalREN. In 2004, the Legislature shifted funding for K-12 connectivity from the University of California to the California Department of Education. This legislation also created the California K-12 High Speed Network (K12HSN) program to coordinate K-12’s participation in CENIC. Network and Internet services are currently provided to the 86 K-12 connection locations, most of which serve as aggregation node sites. These connections provide network access for 79% (7,946) of schools, 87% (861) of school districts, and 100% (58) of county offices of education in California. It is estimated that CalREN serves nearly 4.8 million K-12 public school students. In 2005, the California Community Colleges joined CENIC separately from CSU, with membership equal to that of the University of California, CSU, and the K-12 system. In 2013, Governor Brown and the California State Legislature funded an initiative to help California’s nearly 1,200 public libraries receive high-speed broadband service. The California State Library joined CENIC on behalf of the public libraries and contracted with Califa, a non-profit library membership consortium representing library jurisdictions in California, to administer the program. That work is well underway, with almost 80% of library jurisdictions now connecting to CalREN. Over the years, affiliated educational, governmental, medical research, and cultural institutions throughout the state have been brought into the fold, creating the country's largest statewide research and education network, which now serves more than 20 million users.
