If you have any Basic Load Balancers deployed in Azure Cloud Services (extended support), those deployments will not be affected by this retirement and you don't need to take any action for them.
Here's the official report from Microsoft:
On 30 September 2025, Azure Basic Load Balancer will be retired. You can continue to use your existing Basic Load Balancers until then, but you'll no longer be able to deploy new ones after 31 March 2025.
To keep your workloads appropriately distributed, you'll need to upgrade to Standard Load Balancer, which provides significant improvements including:
High performance, ultra-low latency, and superior resilient load-balancing.
Security by default—closed to inbound flows unless allowed by a network security group.
Diagnostics such as multi-dimensional metrics and alerts, resource health, and monitoring.
SLA of 99.99 percent availability.
