Iran's Internet Is Partially Restored, Cloudflare Radar Data Shows

Why It Matters

Restoring connectivity revives digital commerce, communication and civil society in Iran, while the uneven recovery signals ongoing political and technical constraints that could affect regional stability and foreign investment.

Key Takeaways

• Traffic rose 15x on May 26, hitting 40% of pre‑shutdown levels
• 92% of revived HTTP requests originated from Tehran
• IPv6 address space remains effectively zero despite IPv4 stability
• TCI, IranCell, RighTel, MCCI each saw traffic spikes
• Past brief restorations reversed quickly, suggesting volatility

Pulse Analysis

The February 28 shutdown marked the longest digital blackout in Iran’s recent history, cutting off roughly 99% of outbound traffic and crippling e‑commerce, banking apps, and social platforms. The move was widely interpreted as a strategic response to escalating geopolitical tensions, but it also exposed the fragility of the country’s digital infrastructure, where reliance on a handful of upstream providers makes large‑scale filtering feasible. For multinational firms with supply‑chain exposure to Iran, the blackout forced a rapid pivot to offline channels and heightened compliance risk, underscoring the need for resilient, multi‑path connectivity strategies.

Cloudflare Radar’s real‑time telemetry now paints a nuanced picture of the partial comeback. A 15‑fold spike in data volume and a surge in DNS queries indicate that users are actively probing the web again, yet the traffic ceiling at 40% of historic peaks suggests lingering bottlenecks—likely stemming from selective routing or application‑layer blocks. Tehran dominates the rebound, accounting for more than nine‑tenths of HTTP requests, while peripheral provinces lag behind, hinting at uneven ISP compliance or regional policy differences. Notably, IPv4 address announcements have stayed stable, whereas IPv6 announcements have not recovered, implying that the shutdown leveraged protocol‑agnostic filtering rather than outright routing withdrawal.

Looking forward, the durability of this partial restoration will hinge on political calculations and technical countermeasures. If authorities ease restrictions, businesses can anticipate a gradual return to pre‑shutdown digital volumes, unlocking opportunities in fintech, e‑commerce, and digital advertising. Conversely, a swift reversal—mirroring the brief January recoveries—could reignite uncertainty, prompting investors to demand stronger risk‑mitigation clauses. Continuous monitoring of traffic patterns, DNS activity, and protocol health will be essential for stakeholders navigating Iran’s volatile connectivity landscape.
