As a company, your IT department should already be documenting and creating reports after every server outage. We, as your clients, are simply asking for some more information and transparency behind all these issues.
Look at this example of a public facing Postmortem from another game developer for their clients:

It would not be too much of a hassle as your team is already gathering this information and presenting to the managers and respective leaders. We are asking for a little bit more transparency that will go a long way - just look at how much postive feedback other companies get when being honest with their customers.
This can only benefit everyone.
