Join For FreeMy live OakLeaf Systems Azure Table Services Sample Project demo runs two small Windows Azure Web role instances from Microsoft’s South Central US (San Antonio, TX) data center. I didn’t receive (or misplaced) the usual Pingdom Monthly Report for April, so here’s the detailed uptime report from Pingdom.com for April 2012:
This is the first case of monthly uptime below the 99.95% minimum Windows Azure Compute Service Level Agreement (SLA) guarantee since upgrading the sample app to two instances. My Flurry of Outages on 4/19/2012 for my Windows Azure Tables Demo in the South Central US Data Center post updated 4/30/2012 provides details about the outage on 4/19/2012 and its root cause analysis.
Following is detailed Pingdom response time data for the month of March 2012:
This is the eleventh uptime report for the two-Web role version of the sample project. Reports will continue on a monthly basis.

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.
For more details about the Table Services Sample project or to download its source code, visit its Microsoft Pinpoint entry. Following are Pinpoint listings for three other related OakLeaf sample projects, two of which are live in the South Central US data center:
- Microsoft Codename "Data Explorer" Mashup with "Social Analytics" Data (1/24/2012, live)
- Microsoft Codename “Social Analytics” WinForms Client Sample (11/22/2011)
- SQL Azure Reporting Services Preview Sample (10/24/2011, live)
