A really hand tool has been released in the TechNet Gallery , which allows you to check the availability of all the current Dynamics 365 endpoints.
You can pick up the Dynamics test tool at https://gallery.technet.microsoft.com/Dynamics-365-Network-Test-6e0ccad8.
If you download the PS1 and run it specifying what region you are in after the -OnlineEndPoints parameters.
– NA (North America)
– SA (South America)
– EMEA (Europe, Middle East, Africa)
– APAC (Asia-Pacific)
– JP (Japan)
– IN (India)
– CA (Canada)
– USGOV (United States Government)
– Oceania (Oceania-area)
For the purpose of our testing we chose Europe so the command would read “.\DynamicsNetworkTest.ps1 -OnlineEndPoints EMEA”
It gives you a nice Green Colour if everything is healthy as seen below , or Red if 365 is having issues!
