Uptime Report for my Live OakLeaf Systems Azure Table Services Sample Project: January 2013 = 100.00 %

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

Here’s the report for January 2013, the fifth consecutive month of 100% uptime and the ninth consecutive month of meeting Windows Azure 99.9% uptime SLA:

Note: Pingdom’s report was delayed until 2/18/2013 and arrived while I was in Washington attending Microsoft’s MVP Summit 2013 conference.

Here’s the first page of the detailed uptime report from Pingdom for January 2013:

This is the twentieth uptime report for the two-Web role version of the sample project since it was upgraded to two instances. Reports will continue on a monthly basis.

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.

image_thumb2_thumb_thumb1_thumb_thum[1]

image_thumb9_thumb_thumbI 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.

Windows Azure Armageddon

At 12:54 PM on 2/22/2013, I received the following DOWN Alert message from Pingdom for my OakLeaf Systems Azure Table Services Sample Project demo from my Cloud Computing with the Windows Azure Platform book:

image
When I attempted to run the sample Web Role project at http://oakleaf.cloudapp.net, I received an error message for an unhandled exception stating that an expired HTTPS certificate caused the problem. Here’s the Windows Azure team’s explanation:

Here’s Pingdom’s UP alert at 8:28 PM last night:

Prior to this incident, the sample project had run in the South Central (San Antonio, TX) data center for nine months within the 99.9% availability SLA, as reported in my monthly Uptime Reports. Here’s the latest monthly uptime report data since June, 2011:

Following is the historical report for those services affected by the expired certificate:

imageIt’s obvious that some minor functionary in the Windows Azure bureaucracy missed an item on his or her todo list yesterday. It’s equally obvious that this is a helluva way to run a cloud service (with apologies to Peter Arno and John Luther (Casey) Jones.)

Adrian Cockcroft (@adrianco) noted that “Azure had a cert outage a year ago” in a 2/23/2013 Tweet:

image

Microsoft’s Bill Liang posted a Summary of Windows Azure Service Disruption on Feb 29th, 2012, which was caused by expiration of a “transfer certificate,” on 3/9/2013:

… So that the application secrets, like certificates, are always encrypted when transmitted over the physical or logical networks, the GA creates a “transfer certificate” when it initializes. The first step the GA takes during the setup of its connection with the HA is to pass the HA the public key version of the transfer certificate. The HA can then encrypt secrets and because only the GA has the private key, only the GA in the target VM can decrypt those secrets.

…

When the GA creates the transfer certificate, it gives it a one year validity range. It uses midnight UST of the current day as the valid-from date and one year from that date as the valid-to date. The leap day bug is that the GA calculated the valid-to date by simply taking the current date and adding one to its year. That meant that any GA that tried to create a transfer certificate on leap day set a valid-to date of February 29, 2013, an invalid date that caused the certificate creation to fail. …

Uptime Report for my Live OakLeaf Systems Azure Table Services Sample Project: April 2012

My 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:

image

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:
