Daily executive summary

Compared with the 2026-08-25 snapshot, the 2026-08-26 scan recorded 205 new listings, 0 regressions, and 0 parked unknown transitions.

Where it changed: VM SKUs: 195 new listings, 0 regressions; Azure AI models: 10 new listings, 0 regressions.

Representative changes: Claude Haiku 4 5 model from Anthropic (version 20251001) was newly listed in centralus; Claude Opus 4 5 model from Anthropic (version 20251101) was newly listed in centralus; Claude Opus 4 6 model from Anthropic (version 1) was newly listed in centralus.

What changed: 72 net-new regional listings, 133 restored regional listings.

What this means: The 205 new listings expand the set of regional 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 (2026-08-20 to 2026-08-26): across 6 recorded scans, there were 1,105 new listings and 9 regressions. New listings led on all 6 recorded scans.

Archived commentary and representative evidence

Latest scan: 205 new availability signals and 0 regressions across 4 regions.

Azure AI models: newer models/versions rolling out (10 signals; 10 net-new regional availabilities). SRE impact: new regional model/version options for latency, residency, and model selection. Coverage now ranges from 2 to 4 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 · Azure AI model/version catalog entry for model selection (anthropic.claude-haiku-4-5.20251001); centralus · Azure AI model/version catalog entry for model selection (anthropic.claude-opus-4-5.20251101); centralus · Azure AI model/version catalog entry for model selection (anthropic.claude-opus-4-6.1); centralus · Azure AI model/version catalog entry for model selection (anthropic.claude-opus-4-8.1); and 6 more.

VM SKUs: VM sizes now offered (195 signals; 62 net-new regional availabilities, 133 restored availabilities, up to 1 prior disappearance). SRE impact: more compute shapes for right-sizing, performance, and cost tuning. Coverage now ranges from 2 to 18 of 64 monitored regions. The noisiest affected signal was unavailable 100.0% of prior observations. Expansion pattern: regional expansion of an existing signal; restored regional signal. 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.

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

Help make this page clearer

Two short answers; GitHub will open a draft for your review. No Forms, token, or automatic submission.

This repository is public. Review the text and image for private details. Opening the draft sends text/context to GitHub in its URL. Pasting or attaching an image uploads it to GitHub immediately.

Describe the desired outcome in plain text. This becomes the issue's ### Objective. After reviewing the issue, a maintainer can add azure-backlog to queue it for a scheduled agent; the website does not add that label or start a run.
