Tracking Internet Disruptions in Ukraine: Insights from Three Years of Active Full Block Scans
F. Holzbauer, Sebastian Strobl, Johanna Ullrich
We present results from ongoing ICMP-based /24 block-level measurements, provide aggregated datasets to the research community, and share additional context on Internet disruptions observed during the war in Ukraine.
What we publish
We provide aggregated /24 block-level data only:
- Number of responding IPs per timestamp
- Mean and variance of RTT
- The AS that is announcing the block in BGP
- Ever-active IPs per month
What we do not publish
The raw dataset contains individual Ukrainian IPs and their responsiveness.
Publishing this data could put people and networks at risk.
In case your research requires access to IP-level data, we offer to provide anonymized IP data.
Please include this information in your request.
Release will only be reconsidered in collaboration with Ukraine’s national CERT after the war.
How to request access
Researchers can request restricted access.
Please send an email to: measurements@sba-research.org
Your request should include:
- Full Name
- Institution / Affiliation
- Research goal / Intended use of the data
Requests that do not include this information cannot be processed.
