OMG! Summary of the 3rd Open Measurement Gathering (OMG) Ask Me Anything (AMA) event

On June 25, 2025, the Open Measurement Gathering (OMG) held a public event, “Open Measurement Gathering AMA”, featuring Censored Planet, IODA, OONI, and Measurement Lab. This was a chance for the OMG group to share project updates, future plans, and gather questions and feedback from the Internet freedom community. Each measurement group presented for 30 minutes followed by Q&A.

This public virtual event was inspired by the past two OMG convenings (public reports 1 and 2) at which OMG groups have shared exciting updates to their platforms, tools, and/or datasets before sharing with the broader Internet freedom community. For the third OMG convening, the groups decided to share previewing updates publicly to encourage community feedback.

During the event, OMG groups gathered feedback and answered questions from the Internet freedom community directly. At the end of this post, find some key questions from the community and our answers. You can also watch the presentations and listen to the full Q&A for each session.

The OMG AMA event was especially intended for advocacy organizations, digital rights researchers, anti-censorship tool developers, journalists, lawyers, activists, policy makers, and funders. At its peak, we had about 60 folks joining us from around the world. The OMG groups truly appreciate those who could attend, and we hope to host more joint events in the future!

Presentation Summaries

🛰️What Censored Planet Does

Slides and Recording

Censored Planet is a research team at the University of Michigan building scalable systems and novel techniques to protect users from online censorship, surveillance, and the digital divide. Our work lies at the intersection of Networking, Security & Privacy, and Internet Measurements. We take a data-driven approach to detect and defend against powerful network intermediaries and government threat actors. Our observatory runs daily remote measurements to monitor which domains are blocked across over 200 countries, collecting longitudinal, ethically gathered data.

🆕 Recent and Upcoming Features

This API is a major milestone in our mission to make the Censored Planet data open, accessible, and actionable. It empowers the community to build custom dashboards, perform time-series analysis, and automate censorship detection pipelines.

This statistical fairness is essential for presenting global censorship patterns responsibly—especially in regions where measurement coverage is still limited.

The new dashboard also features an Explore page that gives users direct control over the data they want to analyze. The landing page of the dashboard leads the user to an Explore page, which gives users the possibility to interactively analyze the data. Users can select a specific country, define a time window (up to 6 months), choose the protocol of interest, and select up to 10 domains to focus on. The dashboard then fetches the relevant aggregated data from our GraphQL API and presents a series of detailed visualizations tailored to that selection.

A central part of the Explore page is a table showing each domain alongside its category, the network and subnetwork where it was tested, the number of probes performed, and the unexpected rate—that is, the percentage of probes that encountered some form of interference. To provide temporal context, the dashboard includes an Outcome Timeline, which visualizes how probe results change over time. For each day in the selected window, users can see how many measurements succeeded normally and how many were disrupted, along with a breakdown of the specific types of interference detected.

The dashboard also offers a network-level view that breaks down probe outcomes by ASN and subnetwork, helping uncover whether censorship is uniform across providers or targeted to specific ISPs. Finally, we include a sunburst chart that provides a visual summary of how measurements break down proportionally across outcomes.

🌐 What Measurement Lab (M-Lab) Does

Slides and Recording

M-Lab measures the Internet, saves the data, and makes it universally accessible and useful.

🆕 Recent and Upcoming Features

🐙 What OONI Does

Slides and Recording

The Open Observatory of Network Interference (OONI) is a nonprofit organization that builds free and open source network measurement tools that anyone can use to measure and detect various forms of internet censorship. OONI publishes network measurements collected from around the world as open data in real-time.

🔍 What IODA Does

Slides and Recording

IODA provides a public dashboard showing internet connectivity measurements to monitor Internet infrastructure connectivity and detect Internet outages. IODA is hosted by the Internet Intelligence Lab at Georgia Tech. Users across the globe rely on IODA to track and monitor Internet connectivity. IODA also provides a valuable open-data source for the technical research community that inspires collaboration and spurs researchers to publish scientific literature in the Internet measurement space.

Key Questions From Community

Q: Are there efforts to measure the broader impacts of internet interference (economic, social, political)?

A: For economic impact, we refer you to the methodology implemented in this study from Brookings Institute. There is interest to build upon existing work, however, deeper analysis will likely require collaboration with experts in other fields.


Q: How is AI being used in internet measurement work?

IODA: The Internet Intelligence Lab at Georgia Tech is using AI to classify networks (e.g., identifying government or residential ASNs). Potentially, AI agents could be employed on our dashboard that would allow users to query and interact with measurement data directly. We have also considered using LLMs to help identify potential causes of Internet outage.

M-Lab: One potential use of AI is to help non-technical users to have better access and analysis of Internet measurement data. It is something we would be interested in exploring with partners.


Q: For funding, is there any possibility of becoming for-profit to reduce reliance on support from specific governments?

A: It’s important to OMG groups to maintain their non-profit status, whether as part of a larger entity or independently, due to the nature of their work to make data publicly available, trustworthy, and actionable, especially for the Internet freedom community. In addition, some open Internet measurement tools rely on their communities to collect the data, and we would not want our user community to worry about data being monetized. However, there are options OMG groups could pursue to generate revenue such as data analysis services.

Q: Is it feasible to predict internet outages/censorship events?

CP: Not really — forecasting outages or censorship in advance remains out of reach. However, Censored Planet is developing an early censorship warning system that leverages spikes in Google Trends VPN search terms to flag emerging censorship within a day of onset, even though it cannot predict events ahead of time.

IODA: In our recent paper, Destination Unreachable, we conducted a longitudinal and interdisciplinary study of shutdowns compared to outages and identified political and technical signatures of each. Potentially, these findings could be used to provide an early indicator of an outage demonstrating the signatures of a shutdown versus a spontaneous outage. Read more about the study here.


Q: Can users subscribe for updates?

A: Join the Keep It On and OTF-Talk listservs for updates in the internet freedom community. To join OTF-Talkб go to https://www.opentech.fund/ and scroll to the bottom of the website to request. To join Keep It On, email keepiton-request@lists.riseup.net and request to join.

OONI: You can subscribe to the ooni-talk mailing list for regular OONI updates.

M-Lab: Join our Discuss Google group to get access to M-Lab data, receive updates, and be part of M-Lab community discussions.


Q: Can users define custom alerts for Internet disruptions or censorship events?

A: Yes.

IODA: IODA has an outage detection system that produces alerts for abnormal drops in connectivity signals. You can read more about this outage system in our User Resource Hub. These alerts and outage summaries are visible in our dashboard and accessible via the API.
