Azure default access change could break apps overnight if devs stay unaware

Microsoft will retire default outbound internet access for Azure VMs after September 30, potentially disrupting existing DevOps workflows. While current deployments stay untouched, any new changes will require explicit networking setup. Developers who rely on Azure’s defaults may face silent failures. Security teams welcome the move, but without urgent preparation, organizations could face outages, broken pipelines, and summer surprises hidden in their own infrastructure.
