Maintenance has been completed on Global Service Monitor.
Application Insights is planning maintenance on the Global Service Monitor (GSM) infrastructure which may result in periods where a single region stops active monitoring during the maintenance window. 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. Recommendations for test configuration can be found here: https://technet.microsoft.com/en-us/library/jj860368(v=sc.12).aspx.
We will maintain this blog post to keep you informed each day on the locations which will be affected by the maintenance so that you may plan accordingly.
For additional questions on the GSM service level agreement, please see https://technet.microsoft.com/en-us/library/jj860445.aspx
We understand that customers rely on Application Insights as a critical service and apologize for any inconvenience during this maintenance window.
