Iran's Internet is partially restored, Cloudflare Radar data shows
Curated from Cloudflare Blog
When geopolitical tensions trigger internet shutdowns, SREs often assume their observability tools vanish along with the connectivity. This report serves as a critical reminder that external data sources can provide vital continuity during internal outages. By analyzing global traffic patterns from providers like Cloudflare, teams can infer the health of targeted networks even when internal monitoring agents are silent. This external visibility is not merely academic; it directly impacts incident response strategies. If your organization operates in or serves regions prone to such disruptions, relying solely on internal dashboards is a single point of failure. You must integrate third-party network intelligence into your war room protocols to distinguish between local infrastructure failures and regional censorship. Establishing these alternative data feeds ensures you can assess service impact and communicate effectively with stakeholders when your primary view goes dark.
Cloudflare Radar data confirms early indications of a partial Internet restoration in Iran, nearly three months after the shutdown began. Traffic spikes and DNS queries have risen, but network activity is currently just 40% of pre-shutdown levels.
