Re: Windows can deliver clouds, but it takes a week to recover your data
I think he is referring to a brief SQL Reporting Outage in one Azure region in the USA (USA East)
SQL Reporting was down for a few hours, and there was zero consequential data loss. A few customers had to wait up to 4 days to get access to their data again. If customers cared about resilience / fault tolerance then they would likely have used 2 Azure regions anyway and would not have been affected.
Whilst that sucked, its still historically a much more reliable service than say Amazon provide.
Also as it is based on Hyper-V which benchmarks show is much faster and more efficient than any Linux based hypervisor, and therefore it gives better performance: http://virtualizationreview.com/blogs/the-schwartz-cloud-report/2013/02/azure-bests-amazon-in-storage-shootout.aspx
