HEAnet's e-infrastructure services support approximately 210,000 students and staff (third-level) in Ireland, and approximately 800,000 students and staff (first and second-level) relying on the HEAnet network.[1] In total, the network supports approximately 1 million users.[2]

Established in 1983 by a number of Irish universities,[1] and supported by the Higher Education Authority, HEAnet provides e-infrastructure services to schools, colleges and universities within the Irish education system. Its network connects Irish universities, Institutes of technology in Ireland, the Irish Centre for High-End Computing (National Supercomputing Centre) and other higher education institutions. It also provides internet services to primary and post-primary schools in Ireland (HEIs) and research organisations.[3][4]

HEAnet also hosts a mirror service, which acts as a mirror for projects such as SourceForge, Debian, and Ubuntu.[5]

In 2017, HEAnet announced additional investment in "100Gbps [services] to boost bandwidth accessed by [...] 216 academic locations around Ireland".[6][7]
