Maintenance has been completed on infrastructure for Application Insights Availability Web Test feature.
Necessary updates were installed successfully on all nodes, supporting Availability Web Test feature.
During this timeframe some customers may experience very short availability data gaps in one test location at a time. We will make every effort to limit the amount of impact to customer availability tests, but customers should ensure their availability tests are running from at least three locations to ensure redundant coverage through maintenance. Please refer to the following article on how to configure availability web tests: https://azure.microsoft.com/en-us/documentation/articles/app-insights-monitor-web-app-availability/
We apologize for any inconvenience
