Hello @Ian Lowe

I understand how concerning this sudden increase would be, especially given that your daily costs have remained around €0.15 for several years.

The first step is to determine whether the €832 amount is a forecasted cost or an actual charge, and identify which service or resource is contributing to the increase.

I recommend checking the following in the Azure portal:

Go to Cost Management + Billing → Cost analysis.

Set the date range to 11 September 2026 and select the Daily costs view.

Check the actual cost and compare it with the previous days.

Group the cost by Service name and then by Resource to identify the resource responsible for the increase.

If available for your billing account, review Invoice details to determine whether the amount represents an actual billable charge or only a forecast/estimate.

Also check whether any resources were newly created, scaled up, or experienced an unusual increase in usage around 11 September.

If the €832 amount is confirmed as an actual charge and you cannot reconcile it with your resource usage, I recommend opening an Azure Billing support request so the billing team can investigate the applicable meters and usage records.

If you suspect that the increase may be related to unauthorized usage or a compromised resource, it would also be important to review the affected resource's activity and access logs and follow your organization's security incident process.

I Hope this helps. Do let me know if you have any further queries.

Thank you!

Microsoft agreed to drop the service charge after I explained that the service charge I accidentally signed up for was completely accidental, had never been used and was not appropriate for my service.
