In that work we proved the potential of this approach to dramatically increase the accuracy of IODA’s outage detection applied to its Internet Background Radiation ”connectivity liveness signal” (IBR). In 2019, we published a paper at the TMA network measurement conference where we proposed and evaluated this method with actual outage data. In the last two years, we have developed-in collaboration with University of Strasbourg, France and the Internet Initiative Japan (IIJ) Research Labs-an automated outage detection method based on Seasonal Auto Regressive Integrated Moving Average (S-ARIMA) models. ![]() This sub-task aims at improving IODA’s accuracy and support for additional data sources. 1.1 Improve our S-ARIMA-based outage detection module Such improvements also significantly reduce the effort to operate, maintain and upgrade IODA’s operations and thus have a positive impact on its sustainability. In addition, in this task we propose improvements to IODA’s architecture that will enable the addition and combination of more data sources, as well as safeguard its maintainability thus improving its effectiveness. In this task we intend to make further progress in applying this type of data. Our analysis of new data sources, in collaboration with a large content delivery network (CDN) operator, has been proven a successful strategy: for example, in November 2019 and in early 2020, we identified several outages affecting cellular operators in Iran. Nevertheless, shutdowns of cellular operators are among the main means of government-ordered network interference. Such operators often employ Carrier Grade NAT and for this and other various technical reasons (e.g., lack of disruption at the routing plane weak Internet Background Radiation signal) it is hard to observe, detect, characterize, and analyze shutdowns affecting them. The improvements we plan to make to IODA’s coverage of events are largely targeted towards connectivity disruptions affecting cellular operators. Censorship circumvention tools indeed benefit from a deeper understanding of how, where, and when network interference happens. By making our inferences more accurate, we will be able to better inform the Internet freedom community-and in particular censorship circumvention efforts-in a timely manner. This task aims at improving the accuracy, coverage, effectiveness and sustainability of IODA. ![]() Proposal Tasks Task 1: Improve IODA’s technical capabilities and sustainability We have two directors who are supported by a team of skilled and experienced facilitators and consultants, backed up by an outstanding support team.Engage in outreach and collaboration with censorship circumvention and Internet freedom groups and release timely reports about shutdown events We have also worked extensively internationally, delivering a range of development programmes on behalf of the Department for International Development (DfID). We bring 25 years of experience of working with public, private and voluntary sectors across the UK. We always work with and for our clients, believe in principles over profit and take great pride and pleasure in doing our best. Whether it is a short course of a Leadership Diploma Apprenticeship, having a learner’s simply pass is not enough for our awesome team, which is why we have stunning rates of distinctions and merits in our management apprenticeships and an extraordinary record of retaining our clients. That’s why for over 25 years we continue to retain our clients across the public, private and voluntary sectors and continue to attract extraordinary people with exceptional commitment who support for our learners to go on to do great things. We believe in challenging the status quo and thinking differently we also deliver brilliant training and great customer service in the belief that given the chance every person can find their greatness.
