One Google zone took down UK banks: your Azure zone audit
A power event in one Google Cloud zone, europe-west2-b in London, left Revolut, HSBC, Lloyds and the UK courts' video platform degraded for most of 20 October 2026, and regulators were asking questions within hours. Azure has the same three-zone model in Sweden Central and the same failure mode when resources are left nonzonal, so here is the service-by-service audit, the Sweden Central price of fixing it, and what DORA Articles 11 and 12 already demand.
Azure OpenAI On Your Data is retired: your Foundry IQ path
Azure OpenAI On Your Data retired on 14 October 2026, and Microsoft says the replacement paths are not feature-equivalent: a Foundry IQ knowledge base on Azure AI Search, called directly or through Foundry Agent Service. The guide covers how to find affected data_sources calls, the GA-versus-preview API decision, the parameter mapping, the stricter per-user authorization model, the two-bill cost math, and Sweden Central capacity.
Azure Maia 300: what Microsoft silicon means for Foundry
Microsoft announced Azure Maia 300 on 12 October 2026 with 288 GB of HBM4, 18 TB/s and a claim of 40% more tokens per megawatt, but the chip that reaches Microsoft Foundry by year end is Maia 200, serving OpenAI and open-weight models in unnamed European regions with no price change. What the silicon transition does and does not change for EU data zone deployments, model choice and your evaluation baseline.
Azure's 30 September retirements: what stops working
More than ten Azure items retire on 30 September 2026, and the ones that fail silently are more dangerous than the ones that fail loudly: URL ping tests are deleted from your resources and the ContainerLog table stops receiving data, taking alert rules down with them. A triage guide with Resource Graph queries, Sweden Central cost math for standard web tests and Basic Logs, and a checklist for the Functions v3, Service Bus SBMP and 1 October AI service deadlines.
AWS lost Bahrain for good: your Azure region-loss plan
AWS confirmed on 15 September 2026 that data hosted only in its Bahrain region, and in one UAE Availability Zone, is permanently lost after Iranian strikes damaged multiple zones, proving that multi-AZ design protects availability but not against losing a whole region. For Azure teams in Sweden and the EU, the fix is a classified inventory, GZRS and geo-redundant backups for critical data, and early access to restricted pair regions such as Sweden South.
OpenAI Agents API: US-only residency, your Azure options
OpenAI's Agents API, in public beta since 10 September, packages the Codex harness as a managed runtime with no platform fee, but its documentation limits data residency to the United States and rules out zero data retention even with a self-hosted sandbox. A side-by-side with Claude Managed Agents and Foundry hosted agents, with Sweden Central retail rates, shows runtime cost is a rounding error and residency and identity decide the choice.
Foundry EU Data Zone premium doubles: the Swedish cost math
From 1 September 2026 Microsoft Foundry charges 20 percent over Global for EU Data Zone deployments, up from 10 percent, and 30 percent for Sweden Central regional, while Global pricing stays flat and West Europe regional hits 50 percent. Pay-as-you-go customers only pay the new rate on models launched from today, PTU customers pay immediately, and GPT-5.6 is not yet on regional Standard in Sweden, so here is the cost math and a six-step checklist.
Azure HorizonDB vs PostgreSQL pgvector vs AI Search for RAG
Azure HorizonDB reached public preview at Build 2026: a PostgreSQL-compatible, scale-out engine with vector search built in, up to 128 TB of storage and Sweden Central among the five launch regions. For RAG embeddings on Azure the choice now runs three ways, decided by where the source data lives, how much retrieval quality matters and how close you are to Flexible Server's vertical-scaling ceiling.
Azure Sweden Central Deep Dive: Services, Latency, Residency
Sweden Central is a three-zone region in Gävle whose AI model list now runs ahead of West Europe, but the choice that decides residency, model currency and cost is the Foundry deployment type rather than the region. This deep dive covers verified service and model availability, the EU Data Zone versus regional processing distinction, what data residency does and does not guarantee, DR pairing with restricted-access Sweden South, PTU capacity planning and list-price comparisons.
