As software is becoming ‘everyware’ (Greeneld 2006; Kitchin and Dodge 2011), it is embedded not only in the rhythms of everyday life, but also in the disruptions of the exceptional. Greater vulnerabilities, created by population growth, urbanisation and austerity, ill-equip societies for an increase in extreme weather and political conicts in a twenty-rst ‘century of disasters’ (Vidal 2012). However, at this juncture, people also enact a hopeful digital urbanism. With 6.8 billion mobile subscribers worldwide and double-digit growth (Vinck 2013), they have become generators of big data, documenting their lives in intimate detail, which can be highly valuable during crises. Such digital documentations were used, for instance, to connect individuals, communities, emergency agencies, the media and governments locally and globally, to seek and provide information to organise, coordinate and collaborate in the crises in Mumbai, Port au Prince, Tokyo, Oslo, New York, Boston, Tacloban, Gaza and many others.
