Cloudflare Radar Data Shows Partial Restoration of Iran's Internet, Highlighting Network Resilience Monitoring
Summary
Cloudflare Radar data indicates a partial restoration of Iran's Internet after a nearly three-month nationwide shutdown, with HTTP traffic peaking at 40% of early-year levels. However, announced IPv6 address space remains at zero, highlighting differences in network control mechanisms.
Key Takeaways
Cloudflare monitored Iran's Internet connectivity via its global infrastructure. After 87 days of the second nationwide shutdown (starting Feb 28), Radar observed a marked increase in traffic and DNS queries on May 26 at 11:00 UTC. HTTP traffic spiked briefly at 11:45 UTC, followed by steady growth, with activity roughly 15x the prior week's levels.
Traffic recovery was geographically concentrated, with 91.6% of HTTP requests originating from Tehran. Major ISPs (TCI, IranCell, RighTel, MCCI) all saw traffic increases. Despite the recovery, peak traffic only reached 40% of the maximum activity observed in 2026.
A key technical detail is that IPv4 address space announcements remained relatively stable throughout the shutdowns, while announced IPv6 address space dropped precipitously in January and has not recovered. This suggests the shutdown was achieved via application-layer filtering or whitelisting, not BGP route withdrawal.

Why It Matters
This is a **控制层转移型 (Control Layer Shift)** signal. The control point is shifting from the traditional BGP/IP routing layer (achieving shutdown via IPv4 route withdrawal) to the application/transport layer (achieving precise control via filtering/whitelisting). Value is moving from 'owning physical network infrastructure' to 'owning global traffic visibility and intelligent analytics platforms'. Vendors like Cloudflare, with global Anycast networks, are becoming de facto 'control points' and authoritative intelligence sources for global network status through their data assets. The value of platforms like Radar surpasses the element management of traditional network equipment vendors.
PRO Decision
[Vendors] Networking and security vendors must evaluate their products' deep visibility and control capabilities over application/transport layer traffic, as the technical means of Internet shutdown/control are moving up the stack. They should accelerate the integration of global threat intelligence, traffic behavior analysis, and network status monitoring into their core platforms to address network resilience challenges beyond the BGP routing layer.
[Enterprises] Global enterprises, especially those operating in politically unstable regions, must incorporate network status and resilience monitoring into their business continuity plans. They cannot rely solely on local ISP reports and should leverage third-party global observation data like Cloudflare Radar as a key decision-making input.
[Investors] Focus on platform companies building unique network visibility and analytics capabilities through massive data assets (global traffic, DNS queries). Such capabilities are becoming critical digital-age infrastructure, with commercial value extending beyond security or CDN into areas like geopolitical risk analysis.
