Quota increase

Hello @Alfredo Mapelli

Azure subscriptions start with default vCPU quotas per region. B1s uses 1 vCPU, but the total regional vCPU limit or the B-series family limit for UK South may be at 0 or a very low number on your subscription type (this is common on Pay-as-you-go, Free Trial, and new subscriptions).

Bypass the Broken Portal Form

Since the portal support form isn't saving, use these alternatives:

Option 1 — Azure CLI (fastest)

bash

az support tickets create \  --ticket-name "Quota-Increase-UKSouth-Bseries" \  --title "Request vCPU quota increase for B-series in UK South" \  --description "Please increase the B-series vCPU quota in UK South region. Current limit is blocking VM creation. Requesting increase to [number] vCPUs." \  --problem-classification "/providers/Microsoft.Support/services/06bfd9d3-516b-d5c6-5802-169c800dec89/problemClassifications/e12e3d1d-7fa0-af33-c6d0-3c50df9658a3" \  --severity "minimal" \  --contact-first-name "YourName" \  --contact-last-name "YourLastName" \  --contact-email "******@email.com" \  --contact-country "GB"

Option 2 — Direct quota increase link (skips the broken form)

Go directly to:

portal.azure.com → Subscriptions → [your subscription]→ Usage + quotas→ Filter: Region = UK South, Provider = Compute→ Find "Standard BS Family vCPUs" → click the pencil icon → request increase

This bypasses the Help + Support form entirely and submits a quota request directly.

Option 3 — Microsoft Support via Twitter/X

Post to @AzureSupport — they respond quickly and can create the ticket on your behalf or escalate the broken form issue.

While waiting for quota approval (usually 1–2 hours for small increases, up to 24h):

• Try UK West — quota limits are independent per region and UK West is often less contended
• Try a different VM size in the same family — Standard_B2s or Standard_B1ms may have separate quota headroom
• Check if another region works for a temporary deployment

Hi Alfredo,

Unfortunately, due to capacity issues they have recently restricted new deployments of many v1 - v4 VM sizes (B1 is one that is restricted). This effectively blocks new quota requests for the restricted size families.

You may try equivalent B * v2 series VM instead (request quota if needed), although B v2 is in high demand so may not be available either. B v2 families aren't covered by announcement below, but as I said they may not be available currently due to capacity in your region.

Below is excerpt from relevant Azure Health Advisory TRV3-YHG:

Starting 31 July 2026, Azure will implement capacity growth restrictions for the v1- v4 VM series as part of ongoing investments in newer-generation infrastructure. As a result, new deployments, capacity expansion requests, and quota increase requests for impacted VM series will not be approved. Quota already approved in existing subscriptions for these VM series will not be affected.

Impacted VM series

VM series set to retire in 31 July 2028 and subject to growth controls::

• Compute optimized: F, Fs, Fsv2
• General purpose: D, Ds, Dv2, Dsv2, Av2, Amv2, B, Bs
• Memory optimized: G, Gs
• Storage optimized: Ls, Lsv2

VM series subject to growth controls

• General purpose: Dv3, Dsv3, Dv4, Dsv4, Ddv4, Ddsv4, Dav4, Dasv4
• Memory optimized: Ev3, Esv3, Ev4, Esv4, Edv4, Edsv4, Eav4, Easv4

Customers currently using any of the above VM series may experience restrictions when requesting additional quota or deploying new workloads on the impacted VM series.

This change affects:

• New VM deployments
• VM scale-out activities requiring additional capacity
• Quota increase requests
• Future growth plans on impacted VM series

This change does not affect:

• Existing deployments operating within Capacity currently allocated

Customers can continue running their existing workloads without interruption.

Customers planning future growth, expansion, or new deployments should evaluate migration to newer-generation VM series that provide improved performance, enhanced security, broader availability, and longer-term platform support.

Recommended VM series include:

• Dv5, Dv6, and Dv7 series or variants (Dl/Dd) for general purpose workloads
• Ev5, Ev6, and Ev7 or variants (Ed) series for memory intensive workloads
