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.

imageI 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.

imageThe 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.

Encouraging uptime numbers. Any understanding of why the downtime in April?

@Rob,

From the April 2012 uptime report http://oakleafblog.blogspot.com/2012/05/uptime-report-for-my-live-oakleaf.html):

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 (http://oakleafblog.blogspot.com/2012/04/flurry-of-outages-on-4192012-for-my.html) provides details about the outage on 4/19/2012 and its root cause analysis.
