Ukraine disabled Yandex’s data centre at Sasovo on 8 October and part of its Kaluga site on 9 October, after Russia’s defence ministry said on 6 October that it had struck four Ukrainian data centres. Yemeni government forces said they had captured positions near the Bab el-Mandeb strait, through which most Europe-Asia cable capacity passes. Greece said it would not seek Turkish consent to survey the rest of the Great Sea Interconnector route, and Finland ordered Google to suspend site preparation at Muhos and Kajaani by 23 October. A strike envelope is the area within reach of a given weapon, and the attacks on compute raise the question of whether workloads can continue from facilities outside the same regional strike exposure.
Since Contested Wires last week, Ukraine’s prime minister said on 30 September that Russia had begun massive attacks on Ukraine’s energy infrastructure ahead of freezing weather.1 In the Philippines, subsea cable segments to Singapore and Hong Kong went offline on 2 October, cutting about 300 Gbps, and service returned by 5 October. The trade press report gives no cause and does not link the fault to the Chinese research ship Jia Hai Ke 7.2 Issue 024 reported that Manila had driven that ship from waters off Itbayat on 1 October. Imagery released on 8 October showed a Chinese maritime-militia fishing vessel, a coast guard cutter and a research ship operating in the same area off Taiwan’s east coast. The encounter took place in August, and the disclosure is the new element.34 On the Saudi thread, the General Authority of Civil Aviation confirmed on 7 October that King Khalid International Airport in Riyadh and Abha International Airport were attacked on 6 and 7 October, with three people killed and 36 injured, and the Saudi-led coalition said it had intercepted a Houthi ballistic missile north of Riyadh.5 The Houthis also claimed an attack on a military base at Khamis Mushait, which has not been confirmed, and Turkey and Pakistan agreed on 5 October to deploy forces rapidly to Saudi Arabia under the Makkah pact.67 On UK fibre, BT’s acquisition of TalkTalk out of administration on 5 October, with a government intervention notice the same day, adds a new decision to the consolidation case set out in Issue 007 and followed in Contested Wires.8
The October Short-Term Energy Outlook was released on 6 October, and its fourth-quarter forecast is $14 a barrel above last month’s outlook.9 The EIA finalised its inputs on 1 October, and the outlook states that it does not account for additional supply from the Group of Seven announcement of 2 October covered in Issue 024. For digital infrastructure, higher oil prices feed through to the cost of backup diesel and to contractor escalation clauses, and they would not translate mechanically into data-centre electricity tariffs, which depend on local market structure.
The Reserve Bank of India raised its repo rate by 25 basis points to 5.50% on 7 October, its first rise since February 2023, according to financial news reports.10 The effect on rupee borrowers depends on their benchmark, reset terms and hedging. The euro reached a 17-month low against the dollar on 5 October, which affects dollar-reporting investors with euro revenue through translation.11 The European Central Bank raised its deposit facility rate to 2.50% on 10 September.12
The Russian defence ministry said on 6 October that it had struck the Parkovyi, Ukrtelecom, Giga and Podolskyi data centres, with the stated aim of reducing Ukraine’s communications capabilities, a claim not independently confirmed.13 Parkovyi, in Kyiv, reported on 1 October that its facility was critically damaged and had stopped operating, and that it had moved customer data to backup sites in the European Union.14 Data Center Dynamics lists eight Ukrainian operators with damaged facilities in recent weeks, including Vodafone Ukraine, Cosmonova and Ukrtelecom, and notes that it is not known whether they are all separate sites.1516
Ukraine then struck Yandex’s data centre at Sasovo, in Ryazan Oblast, on 8 October. Yandex said the strike caused a fire that forced the site to cease operations, and the Yandex Cloud status page recorded a power outage in one availability zone. Data Center Dynamics described it as the first major data centre taken down in Russia during the conflict.15 On 9 October Yandex said that several modules at its Kaluga data centre were disabled.1718
Sasovo housed two of Yandex’s three Nvidia A100-based supercomputers according to the company’s earlier disclosures, and Yandex has not confirmed whether those systems were damaged. A loss of AI training capacity should not be treated as established.15
Separate sites can share exposure in two ways. A regional strike campaign can reach several facilities in the same area, and a shared power supply or network link can be a single point of failure for facilities that look independent. Operators and investors with positions in or near the conflict could test how much contracted revenue would continue from replicas outside the affected region, how quickly workloads can move there and whether the replicas rely on the same power or network links. Force majeure wording in compute contracts may also warrant review.
The positions include Mocha and Dhubab in Taiz governorate, and Yemen’s defence ministry later said Mocha had fallen. A Houthi military spokesman said the group still controls its battlefield gains and called the reports fabricated.6
The underwriting question is whether a repair ship can safely reach a damaged cable, in addition to whether a cable fails. Doug Madory of Infoblox told Rest of World that a repair might take one to two weeks depending on the availability of a ship, while the last cuts in this waterway took months because the repair ships needed assurances they would not be fired upon.19
Rest of World reports that more than 90% of data capacity between Europe and Asia runs through cables under the Red Sea, and describes Bab al-Mandab as a strait less than 32 kilometres wide.19 Citing a person familiar with the deal who asked not to be named, Rest of World reports that Google paid a premium in September for a pair of fibre strands along Turkish state pipelines. That single account does not provide a like-for-like price benchmark for other routes. The report also says that Google and Meta have begun routing some live traffic through a land route across Iraq that they had previously kept in reserve, and neither company responded to requests for comment.19 Iraq signed a contract with Ooredoo on 10 September for an underground route from Al-Faw, and Microsoft said on 23 September that it plans to invest more than $400m in subsea and land links across the Middle East by 2030.19
Route concentration at one narrow strait, the safety conditions for repair ships and the price and delivery risk of land alternatives are the variables an operator could act on. Cable investors may wish to test repair-time assumptions that include safe access, and the share of capacity with a tested terrestrial alternative. Rest of World describes no new cable fault.
ProtoThema reported on 5 October that Athens will not seek Turkish permission for the remaining surveys of the Great Sea Interconnector, the planned Crete-Cyprus power cable, and that the project will proceed. Greek City Times also quoted Foreign Minister Giorgos Gerapetritis calling any attempt to obstruct the project inconceivable.2021 ADMIE, Greece’s grid operator, says about 60% of the required surveys are complete. The outstanding surveys lie between Kasos and Cyprus, in waters where Greece and Turkey have competing maritime claims, and ADMIE is finishing preparations to resume them while it discusses with the government when to request a survey vessel and issue a navigational warning to shipping (NAVTEX), with no dates given.21
Turkey’s NAVTEX 0953/26, valid to 25 October, covers an Oruç Reis survey of a proposed gas pipeline route between Turkey and northern Cyprus, as covered in Issue 024. That survey is on a different route from the interconnector surveys.21
The Great Sea Interconnector is a power cable, so its read-through for telecom cable owners is narrower. A data-cable project crossing the same disputed waters would also need to survey and lay cable along its intended route without agreement between the two states. Sponsors and lenders could test schedules against that dependency and read contracts for delay and standoff clauses.
Tuike Finland Oy, Google’s local entity, must suspend significantly environment-altering preparatory work at its planned data-centre projects in Muhos and Kajaani until the environmental impact assessments are complete, the Licensing and Supervision Agency (LVV) said in a press release on 6 October. The suspension covers forest clearance, earthworks, drainage and access infrastructure, and the agency says extensive preparatory measures have already been carried out.22 Tuike must give a written explanation by 14 October and the suspension must take effect no later than 23 October, and the agency is considering enforcement, possibly with a conditional fine, if the company does not comply.22 Capacity reports more than 300 hectares of forest cleared across the two sites.23
The order is environmental enforcement against one company, and the reporting describes no sovereignty dispute and no action aimed at US technology investment as such. Google said it fell short of its own standards and had acted in good faith under the Forestry Act, and Finland’s environment minister said projects would likely be delayed.24 The sites form part of the €13bn Finnish programme announced in September.25
On 8 October the French group Sesterce announced an investment of over €10bn in a data-centre campus at the former Kaipola paper mill in Jämsä. The first phase of 200 MW has works planned to start in 2026, capacity is expected to rise to 600 MW in a second phase with no date given, and Sesterce has an anchor customer it has not named. Over the longer term it aims for more than one gigawatt of AI capacity in Finland, in line with market demand.26 Those are announced plans, and the campus is not yet operational capacity.
Announced investment does not show that an environmental assessment is complete or that a delivery schedule is secured. Investors in European compute could ask what spend and delivery commitments are already exposed at a site if an assessment requires redesign or a long suspension, and whether brownfield plots such as former industrial sites carry lower permitting risk than cleared forest.

|---|---|---|---|
| BT Group / TalkTalk Acquisition out of administration (consumer business and PlatformX wholesale arm) | c.£400m cash impact | 5 Oct 2026 | BT has not disclosed a price and estimates a cash impact of about £400m in its 2027 financial year, covering the acquisition consideration, transaction and administration costs, working capital needs, about £60m of trading losses for the rest of the year and around £100m it will no longer receive from TalkTalk that would otherwise have gone to Openreach. Culture Secretary Lisa Nandy issued a Public Interest Intervention Notice under section 42 of the Enterprise Act 2002 on the same day, and the CMA must report by 19 October.8 BT Group; Capacity. |
| Boost Run / Cohere GPU cloud contract | $525.6m | 6 Oct 2026 (disclosed) | Boost Run disclosed in a Form 8-K signed on 6 October an agreement dated 30 September 2026 under which Cohere will lease dedicated GPU cloud infrastructure for roughly five years per rack from acceptance of each rack, with initial acceptance expected to begin in the second quarter of 2027, and Data Center Dynamics reported it on 8 October. Cohere has committed to pay about $525.6m over the term, part of it prepaid. If a specified minimum amount of infrastructure has not been accepted by 15 July 2027, Cohere may terminate and receive a refund of all prepaid amounts, and if the minimum has been accepted it may terminate the order for infrastructure not accepted by that date and receive a refund of the related prepaid amounts.2728 Boost Run; Data Center Dynamics. |
| GlobalFoundries / TSMC Silicon interposer supply agreement | $2bn over five years | 8 Oct 2026 | GlobalFoundries signs a five-year agreement worth $2bn with TSMC for the production of advanced packaging components at Malta, New York, with a volume ramp from the first half of 2028. Advanced packaging sits in the supply chain for AI accelerators, which makes the agreement relevant to the compute capacity that data-centre operators depend on.29 GlobalFoundries; Data Center Dynamics. |
| Risk Vector | Level | Investor Implication | Status |
|---|---|---|---|
| Physical Targeting of Compute | High | Russia’s defence ministry named four Ukrainian data centres as struck on 6 October, and Ukraine disabled Yandex’s Sasovo site on 8 October and part of Kaluga on 9 October. Facilities that share a strike envelope may warrant underwriting as one exposure. | Escalated |
| Red Sea Corridor | High | Fighting near Bab el-Mandeb, with claims and denials on both sides, puts at risk the waterway through which more than 90% of Europe-Asia data capacity is reported to run, and Google is reported to have paid a premium for a land alternative. | New |
| Eastern Mediterranean Route Risk | Elevated | Greece’s refusal to seek Turkish consent for the remaining Great Sea Interconnector surveys and Turkey’s separate pipeline survey to 25 October keep survey consent contested around Cyprus. The interconnector is a power cable, and a telecom cable project in the same waters would face the same survey dependency. | Continuing |
| Permitting and Site Delivery | Elevated | LVV’s order shows a regulator suspending preparatory works begun ahead of an environmental assessment, with a stop date of 23 October. | New |
| Cost of Capital | Elevated | Rate and currency moves differ by exposure. The Reserve Bank of India raised its repo rate to 5.50%, the euro is near a 17-month low and the EIA forecasts Brent near $96 for 2026, which bear respectively on rupee debt service, dollar translation and fuel costs. | Continuing |
| UK Fibre Market Structure | Elevated | The Public Interest Intervention Notice on BT’s acquisition of TalkTalk, with a CMA report due on 19 October, and the CMA process on nexfibre and Substantial, with a final report due on 15 December, put two regulatory decisions into the next ten weeks. | Escalated |
| Asset Class | Direction | Key Variable | Read-Through | Stance |
|---|---|---|---|---|
| Data Centres (Hyperscale / AI) | Mixed | Physical security and site delivery | Reciprocal strikes and Finland’s order sit against the Boost Run contract, whose acceptance deadline writes delivery risk into the commercial terms. | Selective |
| Subsea Cable | Weakening | Corridor concentration and survey access | Fighting near Bab el-Mandeb concentrates risk on the Red Sea corridor, and the Greek position on the Great Sea Interconnector surveys illustrates how disputed waters can hold up cable projects, although that project is a power cable. | ⇅ Active Watch |
| Fibre / Backbone | Mixed | Regulation | The intervention notice on BT/TalkTalk and the CMA process reshape UK structure, and terrestrial routes through Iraq and Turkey gain value. | Selective |
| Towers / RAN | Mixed | Rate sensitivity | Standing position unchanged. | Neutral |
| Satellite / LEO | Mixed | Interference environment | Standing position unchanged. | Watch |
| Power for Digital | Strengthening | On-site generation, storage and resilient supply | On-site generation and storage address supply interruption, not direct physical damage, and Yandex’s Sasovo site lost power in one availability zone after a single strike. | Overweight |
| Variable | Score | Level | Change | Driver this week |
|---|---|---|---|---|
| Route & Corridor Resilience | 96 | High | +1 | Fighting near Bab el-Mandeb, where repair ships may need safety assurances, and the Greek position on the Great Sea Interconnector surveys add to routes already contested.1920 |
| Permitting & Regulatory Timeline | 85 | High | +1 | LVV’s suspension order at two Google sites could delay delivery, and the CMA’s report on BT/TalkTalk, due 19 October, could set conditions on the acquisition.228 |
| Power Access & Energy Security | 89 | High | +1 | The power outage at Yandex’s Sasovo site and the EIA’s higher Brent forecast.159 |
| Sovereign & Security Compliance | 85 | High | +1 | Greece’s refusal to seek Turkish consent leaves the survey of the remaining interconnector route dependent on a disputed maritime boundary.20 |
| Cyber Posture vs. State-Linked Threats | 78 | High | — | The incidents this week were physical. |
| Committee on Foreign Investment in the United States (CFIUS) & Foreign Investment Review | 72 | Elevated | — | No new foreign-investment screening item was reported this week. |
| Hardware Supply-Chain Optionality | 63 | Elevated | — | The BIS 50% Rule suspension is expected to run to 10 January 2027 under the extended US-China truce, with no formal extension notice reported in the cited 2 October analysis.3031 |
| Exit Narrative Under Geopolitical Scrutiny | 79 | High | +1 | A higher Indian policy rate could affect rupee debt service, a weak euro affects translation for dollar-reporting investors, and Cohere’s acceptance deadline puts delivery risk into contract terms. Each bears on exit timetables only for platforms with that exposure.101127 |
