I have been in the position of implementing a client on a API I do not control. The owners of the servers (colleagues but in a different country) do not seem to know what logs are.
We get random failures from the server. I can pin down to the second when they occur (not closer because of network lag). I suspect that the server is failing under load, but the way I would find out is to... Read the logs.
My foreign colleagues do not respond to me, ghost me entirely, when I ask them to inspect the logs.
Perhaps it is a Windows/Azure thing?
