Service Status for Maintenance on hosts or Redis Service
When maintenance is carried out on the Redis Cache hosts or Redis Services, no indication of this is given anywhere.
We need to be forewarned about maintenance.
When monitoring starts detecting issues we are then ready for it or at least know why we are getting the connection errors or timeouts.
Currently when maintenance is done:
Azure service status => ZERO INDICATION
Azure Planned maintenance => ZERO INDICATION
Health Alerts => ZERO INDICATION
Redis Cache Health => ZERO INIDCATION

We have also experienced multiple (!) major incidents in our applications because of random maintenance events, in which our cache was completely unresponsive. Please warn users beforehand so we can adapt to them.
We have seen major incidents caused by Redis availability issues, we see exceptions logged in application files when redis is failing, but have no way of identifying the cause.
