A community of people interested in the maintenance different parts of our world, and how they do it, recognizing the often hidden work done in repair, custodianship, stewardship, tending and caring for the things that matter. The Festival of Maintenance is a non-profit community event, run by volunteers. It happened for the first time in London, UK, on Saturday 22nd September 2018. Maintainers can be found in many contexts, including nature, software, infrastructure, communities, industry, information, arts and heritage. The Festival brings together traditional disciplines of maintenance, repair and stewardship, with new forms such as supporting digital products, sustaining open source software, and moderating online communities. The Festival aims to share learning around maintainer skills and tools and how maintenance is resourced and rewarded, and to boost the morale of maintainers across sectors with inspiring ideas and stories. The 2018 Festival of Maintenance sought to start a lasting conversation across communities of maintainers and stewards, building shared practices, and raising awareness more widely of the value of this work and where it sits within our society. In 2019 we're reconvening in Liverpool to explore maintenance in complex and changing times.
