3/6/09—ArcGIS Online was updated Friday night, March 6, to address an issue that was reported recently when connecting to ArcGIS Online map services in web applications. Common web application errors encountered were:

• “An error occurred while processing your request.” or
• “Client found response content type of 'text/html', but expected 'text/xml'."

If you experience any ongoing service availability or performance issues related to this change, please post a description of them to this blog or contact ESRI Support.
