IoT Hub deprecation of support for TLS 1.0/1.1 is postponed

The deadline for [IoT Hub deprecation of support for transport layer security (TLS) 1.0/1.1](https://docs.microsoft.com/en-us/azure/iot-hub/iot-hub-tls-deprecating-1-0-and-1-1) is postponed indefinitely. IoT Hub will continue to support TLS 1.0/1.1 until further notice to ensure compatibility with existing applications and devices. It was previously announced that IoT Hub would deprecate support for TLS 1.0/1.1 on 1 July 2020\. After reviewing customer feedback, we’re postponing the deadline for migration indefinitely. However, all customers should migrate to TLS 1.2 as soon as possible. To learn more about this policy, which covers all of Azure, read [Preparing for TLS 1.2 in Microsoft Azure](https://azure.microsoft.com/updates/azuretls12/). For more information on how to contact us and supported ciphers, read [Deprecation of TLS 1.0 and 1.1 in IoT Hub](https://docs.microsoft.com/azure/iot-hub/iot-hub-tls-deprecating-1-0-and-1-1). **_Correction – 14 April 2020_** _Our previous announcement misstated that Device Provisioning Service would deprecate support for TLS 1.0/1.1 as well. Device Provisioning Service doesn’t support TLS 1.0/1.1 – it supports TLS 1.2 only – so the deprecation notice was unnecessary._ * Azure IoT Hub * IoT Hub Device Provisioning Service * Retirements * Security * [ Azure IoT Hub](https://azure.microsoft.com/en-gb/products/iot-hub/)
