Daily executive summary

Compared with the 2026-08-26 snapshot, the 2026-08-27 scan recorded 108 new listings, 195 regressions, and 0 parked unknown transitions.

Where it changed: VM SKUs: 0 new listings, 195 regressions; Azure AI models: 69 new listings, 0 regressions; AKS extensions: 39 new listings, 0 regressions.

Representative changes: Basic A0 VM size was no longer listed in westeurope; Basic A1 VM size was no longer listed in westeurope; Basic A2 VM size was no longer listed in westeurope.

What changed: 62 first recorded disappearances, 133 recurring disappearances, 108 net-new regional listings.

What this means: Review the 195 regressions against existing regional targets and fallbacks first; treat the 108 new listings as options to validate. These are read-only catalog/list signals, not quota, capacity, or deployment results. Zero new delistings does not establish recovery of earlier missing listings.

7-day context (2026-08-21 to 2026-08-27): across 6 recorded scans, there were 1,182 new listings and 204 regressions. New listings led on 5 scans; regressions led on 1.

Archived commentary and representative evidence

Latest scan: 108 new availability signals and 195 regressions across 33 regions.

VM SKUs: VM sizes withdrawn (195 signals; 62 deprecation candidates, 133 recurring disappearances, up to 1 prior disappearance). SRE impact: capacity planning and SKU fallback lists should be rechecked. Coverage now ranges from 1 to 17 of 64 monitored regions. The noisiest affected signal was unavailable 99.0% of prior observations. Examples: westeurope · Azure virtual-machine size for right-sizing compute (basic.a0); westeurope · Azure virtual-machine size for right-sizing compute (basic.a1); westeurope · Azure virtual-machine size for right-sizing compute (basic.a2); westeurope · Azure virtual-machine size for right-sizing compute (basic.a3); and 191 more.

AKS extensions: extension types now listed (39 signals; 39 net-new regional availabilities). SRE impact: new managed cluster capabilities such as GitOps, policy, or observability. Coverage now ranges from 10 to 58 of 64 monitored regions. The noisiest affected signal was unavailable 100.0% of prior observations. Expansion pattern: first observed anywhere in the monitored regions; regional expansion of an existing signal. Examples: centralus · AKS cluster extension type for managed cluster capabilities (microsoft.test.prasanna.1pbilling); centralus · AKS cluster extension type for managed cluster capabilities (microsoft.test.prasanna.1pbilling2); eastasia · AKS cluster extension type for managed cluster capabilities (microsoft.test.prasanna.1pbilling); eastasia · AKS cluster extension type for managed cluster capabilities (microsoft.test.prasanna.1pbilling2); and 35 more.

Azure AI models: newer models/versions rolling out (69 signals; 69 net-new regional availabilities). SRE impact: new regional model/version options for latency, residency, and model selection. Coverage now ranges from 9 to 31 of 64 monitored regions. The noisiest affected signal was unavailable 100.0% of prior observations. Expansion pattern: first observed in Africa; first observed in Asia; first observed in Middle East; first observed in Oceania; first observed in South America; regional expansion of an existing signal. Examples: australiaeast · Azure AI model/version catalog entry for model selection (cohere.cohere-parse-v5.1); brazilsouth · Azure AI model/version catalog entry for model selection (cohere.cohere-parse-v5.1); canadacentral · Azure AI model/version catalog entry for model selection (cohere.cohere-parse-v5.1); canadaeast · Azure AI model/version catalog entry for model selection (cohere.cohere-parse-v5.1); and 65 more.

What this means for Azure users: review placement and fallback plans using these catalog/list signals before changing production deployments.
