Uptime Report for my Live OakLeaf Systems Azure Table Services Sample Project: November 2013 = 99.99%

My (@rogerjenn) live OakLeaf Systems Azure Table Services Sample Project demo project runs two small Windows Azure Web role compute instances from Microsoft’s South Central US (San Antonio, TX) data center. This report now contains more than two full years of monthly uptime data.

Here’s the detailed downtime report from Pingdom for November 2013:

Update 5/7/2013: Added links to those previous uptime reports currently accessible. I don’t know why some posts are missing from the Internet.

The Azure Table Services Sample Project

See my Republished My Live Azure Table Storage Paging Demo App with Two Small Instances and Connect, RDP post of 5/9/2011 for more details about the Windows Azure test harness instance.

I believe this project is the oldest continuously running Windows Azure application. I first deployed it in November 2008 when I was writing Cloud Computing with the Windows Azure Platform for Wiley/WROX, which was the first book published about Windows Azure.

The application runs the default set of Windows Azure Diagnostics. About 5 GB of Event Counter data provides the source data for my Generating Big Data for Use with SQL Azure Federations and Apache Hadoop on Windows Azure Clusters post of 1/8/2012.
