Azure function app unavailable & availability tests failed
Hi.
We have experienced availability issues with azure function app service yesterday from 12PM to 4:45PM. Until yesterday, our service was always up and running and we have never had failed availability test before that time. Our availability test is configured to ping URL every 5 minutes from 5 different locations (Central US, West US, East US, West Europe and North Europe) and timeout is set to 60 seconds. App service suddenly get back to normal at 4:45PM without our intervention, we haven't done anything.
When calling service from postman at that time, we were getting this "Error: read ECONNRESET"
I have checked azure status history https://status.azure.com/en-us/status/history/ and haven’t found any warning or critical error for July 28th.
How we can investigate this in more details and found out what happened (and why) with our service?
