Update 6/5/2010: Posted missing Azure Uptime Report: OakLeaf Table Test Harness for April 2010 (99.71%) report of 4/30/2010.
Following is the Pingdom monthly report for a single instance of the OakLeaf Systems Windows Azure Table Test Harness running in Microsoft’s South Central US (San Antonio) data center:
The May 2010 data is similar to that for previous four months of Azure’s commercial operation, which began on January 4, 2010. The OakLeaf application is not subject to Microsoft’s 99.9% availability Service Level Agreement (SLA), which requires two running instances.
It’s not known how many, if any, of the 22 outages were planned for, as an example, fabric operating system upgrades.
