“The internet is that last shred of hope because, in the darkness of a blackout, anything can happen and nobody will know.”

In #Iran's digital darkness it's unlikely anyone really knows what damage the regime has wrought.

⚠️ Confirmed: Metrics show a drop in internet connectivity in #Ukraine, also impacting #Moldova, corroborating energy company Ukrenergo's statement detailing a system-wide power emergency involving the disconnection of high-voltage international transmission lines 🔌

There are two graphs in the photo. Graph from NetBlocks showing network connectivity in Ukraine from January 27, 2026, to January 31, 2026. The y-axis represents normalized connectivity, ranging from 0% to 100%, and the x-axis represents the dates. The green line representing Ukraine's connectivity remains normal most of the time period, with a drop on the morning of January 31. The drop in connectivity aligns with a power cut. The minimum and current connectivity levels are indicated as 85% and 86%, respectively. The chart has a dark background with a red circle highlighting the decline at the end of the period.

🗓️ It's Friday evening in #Iran where internet remains heavily filtered 22 full days after the blackout as whitelisting and intermittent connectivity continue to limit Iranians' contact with the outside world. Networks are visible internationally but broadly restricted.

@boud Definitely. Tigray is among the most harmful authoritarian subnational shutdowns in our records, and Ethiopia more generally has been a perpetrator of systematic digital repression over the years.

🗓️ Exactly three weeks ago #Iran imposed a national internet blackout to obscure civilian killings. Whitelisting and heavy filtering are still in effect.

The incident is among the most severe of its kind on record, exceeded in duration only during civil war in Myanmar and Sudan.

⚠️ Update: 20 full days after #Iran imposed a national internet blackout, most ordinary users still face heavy filtering and intermittent service under a whitelist system despite a significant increase in internationally visible networks and datacenters.

⚠️ Update: With #Iran's internet shutdown approaching day 20, many networks are becoming visible internationally.

HOWEVER:

📵 No return to usual: Web still heavily filtered on a whitelist basis.
🔧 Circumvention still needed: The opening of protocols can enable new workarounds.

⚠️ Confirmed: Network data show a disruption to internet connectivity in Kharkiv, #Ukraine, following a combined UAV and heavy rocket artillery assault by Russia targeting energy infrastructure

⚠️ Update: #Iran's internet blackout continues through its 18th day, obscuring the extent of a deadly crackdown on civilians.

Meanwhile, gaps in the filternet are being tightened to limit circumvention while whitelisted regime accounts promote the Islamic Republic's narrative.

🗓️ 17 days after #Iran introduced an internet blackout to mask a deadly crackdown:

- minimal whitelisted service available to some users
- circumvention allows messages to get through
- brief connectivity spikes give false impression of wider restoration

The shutdown continues.

400 hours.
