Hello everyone, It seems that the Azure Storage Account hosting the [MNIST dataset](https://batchaisamples.blob.core.windows.net/samples/mnist_dataset.zip?st=2017-09-29T18%3A29%3A00Z&se=2099-12-31T08%3A00%3A00Z&sp=rl&sv=2016-05-31&sr=c&sig=PmhL%2BYnYAyNTZr1DM2JySvrI12e%2F4wZNIwCtf7TRI%2BM%3D) for the [hyperband](https://github.com/Azure/BatchAI/tree/master/recipes/Hyperparameters/HyperBand) based hyperparameter tuning example is not available anymore : ie that creates an issue...
