Feedly flags an #IP in a threat report. @censysio tells you about the host record, when the IP was last scanned, which ports and services answered, who owns the #netblock, and which other hosts share its certificates. You can now pivot from one to the other in one click:

⚠️ Confirmed: Metrics show a disruption to internet connectivity in Zhytomyr Oblast, #Ukraine, corresponding to the third set of power outages this week as Russia's strategy of drone attacks targeting energy infrastructure during the colder months expands westward

@hey_itsmyturn @netblocks does this include general internet connectivity?

BREAKING: Reports of widespread internet disruptions and websites going dark across North Korea

Last 2 days' network connectivity in North Korea by NetBlocks

Tracking internet outages in Russia? Data center strikes? I just came across an outage monitoring tool from VPN provider Amnezia called Amnezia Pulse that posts on telegram Here is a blog post describing their monitoring technique A good complement to classics like @netblocks

Amnezia Pulse has logged 80 internet disruptions across 36 Russian regions in just over a month. On its map of the past 30 days, regions with three or more reported shutdowns are marked in orange. One or two get yellow. None get green. The Kremlin’s internet crackdown is spreading across the country. Not a problem confined to Moscow. The orange regions have been hit repeatedly. For people trying to communicate, work or get information, each shutdown is another reminder that access can be taken away.

Iran Faces Risk of Another Wartime Internet Shutdown 🔹Iranian economic news outlet Zoomon reported on October 21 that unnamed authorities had issued a binding directive to cut international internet access immediately if there is a renewed assault on Iran. The outlet did not publish the document or identify its issuer. The reported order has not been independently verified, and its scope, exemptions, and conditions for restoring access remain unknown. 🔹Deputy Communications Minister Vahid Yazdanian has separately said renewed war or unrest could bring another shutdown, while suggesting President Masoud Pezeshkian might play a greater role in authorizing restrictions. Former communications minister Ahmad Motamedi identified the Supreme National Security Council as the body responsible for wartime decisions. 🔹The warning follows the prolonged internet blackout that began with U.S. and Israeli strikes on February 28. On May 25, Pezeshkian ordered access reopened after most Iranians had spent 87 days largely disconnected, according to NetBlocks. 🔹Iranian industry representatives reported steep sales losses during previous internet restrictions. Communications Ministry officials have also acknowledged that domestic networks and selective business access cannot replace public connectivity, particularly when customers and suppliers remain offline.

⚠️ Update: Crimea remains largely offline more than 16 hours after Ukrainian drone attacks target Taman substation in Krasnodar Krai, Russia, disrupting the supply of electricity to the occupied peninsula.

⚠️ Confirmed: Network data show internet connectivity has been knocked out in occupied Crimea, amid power outages following Ukrainian drone attacks targeting energy infrastructure 🔌

NASA FIRMS indicates a strike on the 500/220 kV Taman substation in Russia's Krasnodar region. It transfers electricity from southern Russia to occupied Crimea. Crimea is now in a total blackout, while NetBlocks shows internet traffic from the peninsula near zero. #Ukraine

@netblocks seems internet outage in Iran is slowly but surely becoming a thing again. Any status update from you guys?

[#NETBLOCK|#MALI] 4e jour de blocage d’internet et des réseaux sociaux par @Malitel_ml et @Orange_Mali L’enquête @netblocks vient d’être mise à jour avec de nouvelles données des utilisateurs. (par @matteomaillard, via @Yaolri)

@HelloMrBond @hey_itsmyturn @netblocks No network impact observed.

@netblocks keep an eye on Cuba. We are just recovering internet connection cause the dictatorship shutdown the network due massive protests against the regime. Here’s my testing #CubaPaLaCalle #AbajoLaDictadura #netblock

بچه‌های NetBlocks گرم کنید که قراره هر روز پست و توییت بزنید.

Das Militär in #Myanmar geht brutal gegen Proteste vor: Tränengas und scharfe Munition. Gestern wurden min 59 Menschen getötet. Dennoch gehen weiter Zehntausende auf die Straße - inspiriert von #Hongkong und #Thailand. Via @ninabcdefghi - Thread (1/7):

Spezifisch für Myanmar: Um zu verhindern, dass die Polizei Straßensperren der Demonstranten durchquert, hängen sie Frauenkleidung über die blockierten Straßen. Ein Aberglaube besagt, dass der sein Glück verliert, wer darunter entlangläuft. (4/7)

Unterschiede: In #Myanmar ist das Militär bereit, zu töten. Die Menschen müssen vorsichtiger sein als in #Hongkong. Sie können sich nicht nur online vernetzen, weil das Internet blockiert wird. Großer #Netblock in HK würde den Tech-Standort gefährden (5/7)

⚠️ Important: Despite the restoration of observable internet connectivity in #Myanmar, analysis of cellular networks reveals that mobile networks remain disabled nationwide. ℹ️ Most users rely on cell phones for their day to day work, and at protests. 📰

North Korea's internet has been close to zero since Oct 19, per NetBlocks. State websites are down. Worth remembering: only a tiny elite can reach the global internet there. Everyone else uses a closed national intranet. So this mostly cuts the regime's voice to the outside world, not ordinary citizens. Technical failure, power shortage, or deliberate? Unclear.

North Korea hit by widespread internet blackout as state websites go dark

⚠️ Confirmed: Network data show an ongoing disruption to North Korea's already limited internet connectivity. The incident corresponds with the loss of international access to websites under the country's .kp domain.

‼️ BREAKING: North Korea has been largely offline for more than a day. NetBlocks confirms the outage. NK News says nearly every .kp site has been down or unstable, from state news agency KCNA to national airline Air Koryo. The cause is unknown, and nobody has claimed an attack.

A major power blackout has hit Russian-occupied Crimea following reports of damage to the Taman 500/220 kV substation in Russia’s Krasnodar Krai. The substation is a critical node in the mainland electricity link supplying occupied Crimea. NASA FIRMS satellite data reportedly detected a thermal anomaly at the facility, while NetBlocks documented severe internet connectivity disruptions in Sevastopol. Russian-installed authorities confirmed power outages. Reports indicate that electricity was restored in some areas, but further interruptions followed. If confirmed, damage to this infrastructure exposes a strategic vulnerability: Crimea’s dependence on electricity transmission from mainland Russia. The full extent of the damage and the duration of the outages remain unverified. Sources:
