Four New Breakthroughs Reported As Ukraine Forces Cross Siverskyi Donets River

Four new breakthroughs by Ukrainian forces east of Lyman and the Fortress Belt, including crossings of the Siverskyi Donets River reveal that counteroffensive operations continue to gain ground against Russian units.

In keeping with recent Ukrainian military operational security doctrine, they have not confirmed these attacks, nor have they released any other information about units involved or whether this is the fourth phase of Operation Vivaldi. JL

Brendan Cole reports in Newsweek:

Ukrainian forces made notable battlefield advances (including) four breakthroughs along the front line in the Donbas region, east of Slovyansk and Kramatorsk. "Ukrainian forces have crossed the Siverskyi Donets River, a significant natural obstacle." Russian sources fear Ukrainian counterattacks in the Slovyansk and Kramatorsk directions "may have cascading effects and implications for Russian efforts to seize the Fortress Belt." It would mean that Russian troops advancing towards the cities would be difficult. Any push by Moscow towards Slovyansk may be "doomed" due to failure or high casualties if Russian forces cannot recapture forests south of the city of Lyman.

Russia's AI, Cloud Services, Apps and Bot Attacks Shut Down By Ukraine Strikes

Russia's Yandex is the equivalent of Google, Amazon and Uber. It is that country's largest provider of tech services: internet, cloud, AI development, etc. Ukrainian drone and missile strikcs have now badly damaged or destroyed its primary data centers and AI training facilities. 

The result is not just that Russian consumers are frustrated by the disruption - but so is the Russian military, which also depends on them. And, in a particularly helpful side effect for western democracy, Russian bot traffic aimed at the US midterm elections, European concerns about Russian threats (and ancillary interference like inflaming passions in northern Ireland over attempts to revive Orange Order parades) as well as spewing hate and division across the civilized world, has virtually disappeared. JL

Mike Pearl reports in Gizmodo and Jowi Morales reports in Tom's Hardware:

A big chunk of Russia’s cloud and AI infrastructure has been blown up. Services are disrupted, or completely shut down as one of the focal points for Ukraine’s strikes has been Yandex, “a (Russian) version of Google, Amazon and Uber in one.” The third attack, Sunday morning, was devastating, “resulting in the complete shutdown of its data centre." Russian bot traffic has dropped to 0.4% of the maximum number of HTTP requests recorded in the past two weeks. It initially dropped to  57% on Oct. 8, when Ukraine hit a Yandex data center. A second, bigger Yandex campus was then  knocked offline. Yandex’s network traffic has dropped to 30% for Yandex Cloud and 63% for Yandex LLC, resulting in slower services or complete disruption for Russians, who cant use high-speed satellite internet, as Starlink does not work in Russia, while the new Rassvet system had a good number of its satellites fall back to earth after launch. 

Operation Vivaldi Victory Combined Power of Silence, Delusion, Robots

Among the more fascinating - and instructive - lessons from Operation Vivaldi so far, is the fact that it demonstrated the Ukrainians ability to combine hard-won experience with innovative experiments. 

First, Ukraine learned from the failed 2024 counteroffensive and imposed strict operational security: no one was really aware of Vivaldi until four months after it started. This helped first in giving Ukraine's 3rd Corps time to adapt and take advantage of Russia's exposed flanks towards Lyman. But it also played on Russian officers' tendency to lie to their superiors, especially when they are in trouble, which then allowed Ukraine to take further advantage of the Russians' confusion about real conditions and perception that reinforcements weren't needed. The Ukrainians then built on this experiential wisdom by using drones, robots and up-armored vehicles with hardened infantry to exploit the opportunity. The results of this are now clear. JL 

David Axe reports in The Center For European Policy Analysis:

By the time Ukraine's 3rd Corps announced Operation Vivaldi in late September, it had liberated 176 sq. km. of occupied land. By pushing them back across the Zherebets River, the 3rd Corps eliminated 18 months of Russian progress. Which comes down to an age-old truism: every rapid advance risks turning into defeat if the attacker overextends, exposing their flanks to counter-attack. The 3rd Corps understood that it needed to do so quietly because Russian commanders lie to their superiors: a Russian officer won’t admit his unit is losing ground. By not posting evidence of wins, the Russians claim all was well, so no need for Moscow to send reinforcements. (Plus) robots can lead. “Drones, robots and motivated infantry, that’s what the first season of Vivaldi sounds like” The Ukrainians found weaknesses and attacked, first with drones, then with infantry and armor. All in secret. Four months later, the Russians were in retreat. And Vivaldi hasn’t finished.

AI Chip Demand Pushes Samsung To All-Time Quarterly Profit

Samsung Electronics is the world's largest chip manufacturer - but even so, it is defying the law of large numbers with recent demand due to the AI boom. Memory supply is projected to be tight for the next few years, so Samsung will continue to benefit.

It is on track to earn a quarterly operating profit of $80 billion - which is twice what it made in all of 2025. Let that sink in. JL

Kwanwoo Jun reports in the Wall Street Journal:

Samsung Electronics expects quarterly operating profit to exceed $80 billion for the first time, putting the world’s largest memory-chip maker on track to extend its run of record earnings. The staggering preliminary estimate—more than twice what Samsung made for the whole of 2025—comes as it remains a key beneficiary of global demand for advanced chips as companies invest heavily in AI infrastructure and applications. Shares have tripled over the past year, though concerns about the sustainability of the AI investment boom have recently damped investor sentiment. Most analysts and semiconductor executives expect tight memory supply to persist over the next few years, keeping chip prices elevated. 

All Robot Airborne Assaults Becoming Standard Ukrainian Tactic

Innovation in war time moves fast. 

From the first fantastical reporting a few weeks ago of all-robot airborne assaults led by Ukrainian ground drones delivered by aerial bomber drones, this tactic is now becoming a standard tactic in Ukraine's assault operations. It both shocks and confuses the enemy while also saving Ukrainian infantry lives. JL

Jake Epstein reports in Business Insider:

Traditional airborne assaults have been very rare in this conflict as dense air-defense networks threaten air operations. Operation Vivaldi, though, has demonstrated the potential for entirely uncrewed airborne assaults. Rather than risking helicopters, transport aircraft, or paratroopers, drones can drop robots behind enemy lines, and Ukraine's defense industry is working on solutions to advance this concept, as are military units. From Ukraine's robot combat experience, UGVs must balance mobility, range, and payload, while maintaining resilient communications with operators. They are turning the prototype into serial production. "During assault operations, ahead of the infantry, UAVs and loitering munitions always go first" 

Midterm-Threatened Republicans Turn On Trump Over Putin Diesel Sell-Out

Trump's announcement of a deal to buy diesel oil - the price of which has skyrocketed in the US, largely due to the stalemated Iran war - already appears to be failing economically and politically. 

A number of Republican politicians, facing a serious midterm election threat from Democrats wasted no time in coming out publicly against the deal, primarily because the Russian invasion is not viewed sympathetically by a majority of Americans. In addition, economists and business executives are saying that the deal will not reduce the price of diesel at the pump for Americans, making the entire exercise, which Trump evidently believed would benefit his party in the midterms, another policy mistake. JL

Emily Smith reports in The Telegraph:

Republicans fighting in the midterm elections have turned on Donald Trump over his diesel deal with Vladimir Putin. Two have spoken out, with another incumbent in a key state describing the deal as a "grave error" as polls tighten before the vote in November. Other Republicans have also rounded on the US president, suggesting his attempts to assuage energy price concerns may already be backfiring. Experts said the deal would have little effect on US prices at the pump. "It's a grave error by the president. People realise that the sanctions on Russia are appropriate when Russia's invading a country and bombing cities at night."

Operation Vivaldi's Scope Widens As Ukraine Continues Pushing Russians Back

A week ago, reports that Ukrainian troops had crossed the Siverskyi Donets River east of Lyman were dismissed as premature. No longer.

A growing number of experts are pointing to new evidence that the Ukrainian forces, operating again under strict news blackout security, are extending and expanding their counteroffensive operations. The where and how are less significant than the fact of the new momentum. JL

Ryder Blackthorn reports in Frontline Signal:

Ukrainian troops are operating across the Siverskyi Donets river while pressing toward Kryva Luka. The river is a significant natural obstacle. If those reports are accurate and Ukraine can maintain positions on the opposite bank, Russia loses the protection that obstacle provides. It also gives Ukrainian forces additional angles from which to pressure Russian positions south of the river. Kryva Luka adds another complication because the settlement sits near tactically useful high ground. Russia may have to spend more resources simply stabilizing ground it already holds. A counteroffensive doesn’t have to recover enormous amounts of territory to change a campaign.
