Daily executive summary

Compared with the 2026-09-01 snapshot, the 2026-09-02 scan recorded 52 new listings, 343 regressions, and 0 parked unknown transitions.

Where it changed: VM SKUs: 52 new listings, 343 regressions.

Representative changes: Basic A0 VM size was no longer listed in 2 regions; Basic A1 VM size was no longer listed in 2 regions; Basic A2 VM size was no longer listed in 2 regions.

What changed: 4 first recorded disappearances, 339 recurring disappearances, 52 restored regional listings.

What this means: Review the 343 regressions against existing regional targets and fallbacks first; treat the 52 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 (2026-08-27 to 2026-09-02): across 7 recorded scans, there were 984 new listings and 604 regressions. New listings led on 5 scans; regressions led on 2.

Archived commentary and representative evidence

Latest scan: 52 new availability signals and 343 regressions across 3 regions.

VM SKUs: VM sizes withdrawn (343 signals; 4 deprecation candidates, 339 recurring disappearances, up to 3 prior disappearances). SRE impact: capacity planning and SKU fallback lists should be rechecked. Coverage now ranges from 1 to 18 of 64 monitored regions. The noisiest affected signal was unavailable 99.1% of prior observations. Examples: eastus · Azure virtual-machine size for right-sizing compute (basic.a0); eastus · Azure virtual-machine size for right-sizing compute (basic.a1); eastus · Azure virtual-machine size for right-sizing compute (basic.a2); eastus · Azure virtual-machine size for right-sizing compute (basic.a3); and 339 more.

VM SKUs: VM sizes now offered (52 signals; 52 restored availabilities, up to 2 prior disappearances). SRE impact: more compute shapes for right-sizing, performance, and cost tuning. Coverage now ranges from 11 to 11 of 64 monitored regions. The noisiest affected signal was unavailable 98.2% of prior observations. Expansion pattern: restored regional signal. Examples: northcentralus · Azure virtual-machine size for right-sizing compute (d128ds.v7); northcentralus · Azure virtual-machine size for right-sizing compute (d128lds.v7); northcentralus · Azure virtual-machine size for right-sizing compute (d128ls.v7); northcentralus · Azure virtual-machine size for right-sizing compute (d128s.v7); and 48 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.
