Azure Virtual Network SLA Credits & Refunds

Azure's SLA framework treats networking services like Virtual Network as a measurable commercial commitment, not a courtesy. If Virtual Network falls below its monthly uptime target, you can claim credits — but only if you file through the Azure portal with the right billing evidence. This guide covers the exact Virtual Network thresholds, exclusions, and claim procedure.

Frequently asked questions about Azure Virtual Network SLAs

What is the typical SLA uptime guarantee for Azure Virtual Network?

The core Azure Virtual Network (VNet) resource is a free foundational service and does not carry a standalone uptime SLA — there is nothing to credit because there is no charge for the VNet itself. Availability commitments instead apply to the chargeable networking services that ride on top of it: VPN Gateway (99.95% on zone-redundant, 99.9% otherwise), ExpressRoute (99.95%), Azure Firewall (99.95%, or 99.99% across two or more zones), Application Gateway (99.95%), and Load Balancer Standard (99.99%). If Azure fails to meet one of these connected commitments during a billing cycle, you are eligible to receive a portion of the affected service's spend back as a credit.

How do I claim Azure Virtual Network SLA credits after an outage?

Submit a billing support request through the Azure portal: Help + Support → New support request → Issue type: Billing → Problem type: Service credit request. Within two months of the billing period in question, provide the affected Subscription ID and Resource ID, the start and end timestamps of the impacted period, your evidence (Azure Monitor logs, Resource Health alerts, or independent monitoring), and your calculated Monthly Uptime Percentage for Virtual Network. Microsoft validates against its internal incident records before issuing the credit to your billing account.

What exclusions apply to the Azure Virtual Network SLA?

Specifically, NSG/route table misconfigurations, customer-side BGP peering issues on ExpressRoute, and DNS resolution failures using customer-managed name servers are excluded.

Why is it difficult to get refunds for Virtual Network outages manually?

Networking incidents are the easiest to misclassify. A Virtual Network disruption might really be a DNS resolution issue, an upstream peering problem, or a TLS certificate failure — and the SLA only covers what the provider's own infrastructure caused. Distinguishing a true Virtual Network outage from a downstream symptom requires correlated telemetry across multiple layers, which is exactly the data manual claim filers tend to miss.

Azure billing support requests for Virtual Network aren't difficult to file — they're tedious. Each one takes the same kind of subscription-ID, resource-ID, timestamp, and uptime-calculation packaging, repeated for every incident across every subscription you own.
