The paper questions the concept of “ubiquitous city” as a way to describe changing urban environment in a situation of increased Internet access and time spent online. The author suggests the term "digital porosity" to grasp the non-uniformity, limitations and gaps of digital connectivity (technological, material, spatial, social, etc.). Based on the research of internet connectedness and practices of Internet use in the subways of Moscow and St. Petersburg, the paper states that the extension of the Internet zone and the inclusion of new urban spaces do not automatically increase the connectivity of the city, since the latter depends not only on the availability or the quality of internet communication, but also on the intentions and skills of the internet users and their ideas about the comfort and the possibility of internet connection, the role of subway ride in the broader planning horizons.
