Measuring Iran's Internet Collapses
Iran's internet has been dark, in some form, for most of 2026. Two near-total collapses, one in early January after nationwide protests and a second in late February after the start of the war, have left reachability hovering around 1% of pre-collapse levels.
The visualization below is built on ProbeNet, our active-measurement network that runs a weekly ICMP census across global IP space. Filtering that census to addresses geolocated to Iran, week by week and ASN by ASN, is what produces the view you see here.
For the full analysis and methodology, read the companion post: Iran's internet has collapsed twice this year. Here's what we measured.

Post-collapse baseline
Residual reachable surface
On Jan 5, 2026 the reachable surface fell from 100% to 0.6% of peak in a single week. Visible ASNs went from 488 to 47 over the same step — the lattice on the globe is what remains responding.
