 There are a few exceptions and limitations to choosing a VM size:
 
 * Some VM series aren't supported in Azure Machine Learning.
-* Some VM series are restricted. To use a restricted series, contact support and request a quota increase for the series. Please note that for GPUs and specialty SKUs, you would always have to request for quota due to high demand and limited supply. For information on how to contact support, see [Azure support options](https://azure.microsoft.com/support/options/).
